Question:
What is (are) Arrhythmia ?

Answer:
Espaol
                
An arrhythmia (ah-RITH-me-ah) is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.
                
A heartbeat that is too fast is called tachycardia (TAK-ih-KAR-de-ah). A heartbeat that is too slow is called bradycardia (bray-de-KAR-de-ah).
                
Most arrhythmias are harmless, but some can be serious or even life threatening. During an arrhythmia, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.
                
Understanding the Heart's Electrical System
                
To understand arrhythmias, it helps to understand the heart's internal electrical system. The heart's electrical system controls the rate and rhythm of the heartbeat.
                
With each heartbeat, an electrical signal spreads from the top of the heart to the bottom. As the signal travels, it causes the heart to contract and pump blood.
                
Each electrical signal begins in a group of cells called the sinus node or sinoatrial (SA) node. The SA node is located in the heart's upper right chamber, the right atrium (AY-tree-um). In a healthy adult heart at rest, the SA node fires off an electrical signal to begin a new heartbeat 60 to 100 times a minute.
                
From the SA node, the electrical signal travels through special pathways in the right and left atria. This causes the atria to contract and pump blood into the heart's two lower chambers, the ventricles (VEN-trih-kuls).
                
The electrical signal then moves down to a group of cells called the atrioventricular (AV) node, located between the atria and the ventricles. Here, the signal slows down just a little, allowing the ventricles time to finish filling with blood.
                
The electrical signal then leaves the AV node and travels along a pathway called the bundle of His. This pathway divides into a right bundle branch and a left bundle branch. The signal goes down these branches to the ventricles, causing them to contract and pump blood to the lungs and the rest of the body.
                
The ventricles then relax, and the heartbeat process starts all over again in the SA node. (For more information about the heart's electrical system, including detailed animations, go to the Health Topics How the Heart Works article.)
                
A problem with any part of this process can cause an arrhythmia. For example, in atrial fibrillation (A-tre-al fi-bri-LA-shun), a common type of arrhythmia, electrical signals travel through the atria in a fast and disorganized way. This causes the atria to quiver instead of contract.
                
Outlook
                
There are many types of arrhythmia. Most arrhythmias are harmless, but some are not. The outlook for a person who has an arrhythmia depends on the type and severity of the arrhythmia.
                
Even serious arrhythmias often can be successfully treated. Most people who have arrhythmias are able to live normal, healthy lives.
Question:
What causes Arrhythmia ?

Answer:
An arrhythmia can occur if the electrical signals that control the heartbeat are delayed or blocked. This can happen if the special nerve cells that produce electrical signals don't work properly. It also can happen if the electrical signals don't travel normally through the heart.
                
An arrhythmia also can occur if another part of the heart starts to produce electrical signals. This adds to the signals from the special nerve cells and disrupts the normal heartbeat.
                
Smoking, heavy alcohol use, use of some drugs (such as cocaine or amphetamines), use of some prescription or over-the-counter medicines, or too much caffeine or nicotine can lead to arrhythmias in some people.
                
Strong emotional stress or anger can make the heart work harder, raise blood pressure, and release stress hormones. Sometimes these reactions can lead to arrhythmias.
                
A heart attack or other condition that damages the heart's electrical system also can cause arrhythmias. Examples of such conditions include high blood pressure, coronary heart disease, heart failure, an overactive or underactive thyroid gland (too much or too little thyroid hormone produced), and rheumatic heart disease.
                
Congenital (kon-JEN-ih-tal) heart defects can cause some arrhythmias, such as Wolff-Parkinson-White syndrome. The term "congenital means the defect is present at birth.
                
Sometimes the cause of arrhythmias is unknown.
Question:
Who is at risk for Arrhythmia? ?

Answer:
Arrhythmias are very common in older adults. Atrial fibrillation (a common type of arrhythmia that can cause problems) affects millions of people, and the number is rising.
                
Most serious arrhythmias affect people older than 60. This is because older adults are more likely to have heart disease and other health problems that can lead to arrhythmias.
                
Older adults also tend to be more sensitive to the side effects of medicines, some of which can cause arrhythmias. Some medicines used to treat arrhythmias can even cause arrhythmias as a side effect.
                
Some types of arrhythmia happen more often in children and young adults. Paroxysmal supraventricular tachycardia (PSVT), including Wolff-Parkinson-White syndrome, is more common in young people. PSVT is a fast heart rate that begins and ends suddenly.
                
Major Risk Factors
                
Arrhythmias are more common in people who have diseases or conditions that weaken the heart, such as:
                
Heart attack
                
Heart failure or cardiomyopathy, which weakens the heart and changes the way electrical signals move through the heart
                
Heart tissue that's too thick or stiff or that hasn't formed normally
                
Leaking or narrowed heart valves, which make the heart work too hard and can lead to heart failure
                
Congenital heart defects (defects present at birth) that affect the heart's structure or function
                
Other conditions also can raise the risk for arrhythmias, such as:
                
High blood pressure
                
Infections that damage the heart muscle or the sac around the heart
                
Diabetes, which increases the risk of high blood pressure and coronary heart disease
                
Sleep apnea, which can stress the heart because the heart doesn't get enough oxygen
                
An overactive or underactive thyroid gland (too much or too little thyroid hormone in the body)
                
Several other risk factors also can raise your risk for arrhythmias. Examples include heart surgery, certain drugs (such as cocaine or amphetamines), or an imbalance of chemicals or other substances (such as potassium) in the bloodstream.
Question:
What are the symptoms of Arrhythmia ?

Answer:
Many arrhythmias cause no signs or symptoms. When signs or symptoms are present, the most common ones are:
                
Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or fast)
                
A slow heartbeat
                
An irregular heartbeat
                
Feeling pauses between heartbeats
                
More serious signs and symptoms include:
                
Anxiety
                
Weakness, dizziness, and light-headedness
                
Fainting or nearly fainting
                
Sweating
                
Shortness of breath
                
Chest pain
Question:
What is (are) Kawasaki Disease ?

Answer:
Kawasaki (KAH-wah-SAH-ke) disease is a rare childhood disease. It's a form of a condition calledvasculitis(vas-kyu-LI-tis). This condition involves inflammation of the blood vessels.
                
In Kawasaki disease, the walls of the blood vessels throughout the body become inflamed. The disease can affect any type of blood vessel in the body, including the arteries, veins, and capillaries.
                
Sometimes Kawasaki disease affects the coronary arteries, which carry oxygen-rich blood to the heart. As a result, some children who have Kawasaki disease may develop serious heart problems.
                
Overview
                
The cause of Kawasaki disease isn't known. The body's response to a virus or infection combined with genetic factors may cause the disease. However, no specific virus or infection has been found, and the role of genetics isn't known.
                
The disease can't be passed from one child to another. Your child won't get it from close contact with a child who has the disease. Also, if your child has the disease, he or she can't pass it to another child.
                
Kawasaki disease affects children of all races and ages and both genders. It occurs most often in children of Asian and Pacific Island descent. The disease is more likely to affect boys than girls. Most cases occur in children younger than 5years old.
                
One of the main symptoms of Kawasaki disease is a fever that lasts longer than5days. The fever remains high even after treatment with standard childhood fever medicines.
                
Children who have the disease also may have red eyes, red lips, and redness on the palms of their hands and soles of their feet. These are all signs of inflamed blood vessels.
                
Early treatment helps reduce the risk of Kawasaki disease affecting the coronary arteries and causing serious problems.
                
Outlook
                
Kawasaki disease can't be prevented. However, most children who have the disease usually recover within weeks of getting symptoms. Further problems are rare.
                
The disease affects some children's coronary arteries, which can cause serious problems. These children need long-term care and treatment.
                
Researchers continue to look for the cause of Kawasaki disease and better ways to diagnose and treat it. They also hope to learn more about long-term health risks, if any, for people who have had the disease.

The disease is more likely to affect boys than girls. Most cases occur in children younger than 5 years old. Kawasaki disease is rare in children older than 8.
Question:
What are the symptoms of Kawasaki Disease ?

Answer:
Major Signs and Symptoms
                
One of the main symptoms during the early part of Kawasaki disease, called the acute phase, is fever. The fever lasts longer than 5 days. It remains high even after treatment with standard childhood fever medicines.
                
Other classic signs of the disease are:
                
Swollen lymph nodes in the neck
                
A rash on the mid-section of the body and in the genital area
                
Red, dry, cracked lips and a red, swollen tongue
                
Red, swollen palms of the hands and soles of the feet
                
Redness of the eyes
                
Other Signs and Symptoms
                
During the acute phase, your child also may be irritable and have a sore throat, joint pain, diarrhea, vomiting, and stomach pain.
                
Within 2 to 3 weeks of the start of symptoms, the skin on your child's fingers and toes may peel, sometimes in large sheets.
Question:
How to diagnose Kawasaki Disease ?

Answer:
Kawasaki disease is diagnosed based on your child's signs and symptoms and the results from tests and procedures.
                
Specialists Involved
                
Pediatricians often are the first to suspect a child has Kawasaki disease. Pediatricians are doctors who specialize in treating children.
                
If the disease has affected your child's coronary (heart) arteries, a pediatric cardiologist will confirm the diagnosis and give ongoing treatment. Pediatric cardiologists treat children who have heart problems.
                
Other specialists also may be involved in treating children who have Kawasaki disease.
                
Signs and Symptoms
                
The doctor will check your child for the classic signs and symptoms of Kawasaki disease.
                
The doctor will rule out other diseases that cause similar symptoms. These diseases include Rocky Mountain spotted fever, scarlet fever, and juvenile rheumatoid arthritis.
                
Generally, your child will be diagnosed with Kawasaki disease if he or she has a fever that lasts longer than 5 days plus four other classic signs or symptoms of the disease.
                
However, not all children have classic signs and symptoms of Kawasaki disease. Tests and procedures can help confirm whether a child has the disease.
                
Tests and Procedures
                
Echocardiography
                
If the doctor thinks that your child has Kawasaki disease, he or she will likely recommendechocardiography(EK-o-kar-de-OG-ra-fee), or echo. This painless test uses sound waves to create pictures of the heart and coronary arteries.
                
Echo also can help show the disease's effects over time, if any, on your child's coronary arteries. Often, the disease's effects on the coronary arteries don't show up until the second or third week after the first symptoms appear. Thus, this test is done regularly after the diagnosis.
                
Some children who have Kawasaki disease don't have the classic signs and symptoms of the acute phase. Doctors may not diagnose these children until 2 to 3 weeks after the onset of the disease. This is when another common sign of Kawasaki disease occurspeeling of the skin on the fingers and toes.
                
If your child is diagnosed at this point, he or she will likely need echo right away to see whether the disease has affected the coronary arteries.
                
Other Diagnostic Tests
                
Doctors also use other tests to help diagnose Kawasaki disease, such as:
                
Blood tests. The results from blood tests can show whether the body's blood vessels are inflamed.
                
Chest x ray. This painless test creates pictures of structures inside the chest, such as the heart and lungs. A chest x ray can show whether Kawasaki disease has affected the heart.
                
EKG (electrocardiogram). This simple test detects and records the heart's electrical activity. An EKG can show whether Kawasaki disease has affected the heart.
Question:
How to prevent Kawasaki Disease ?

Answer:
Kawasaki disease can't be prevented. However, most children who have the disease recoverusually within weeks of getting signs and symptoms. Further problems are rare.
Question:
What causes Metabolic Syndrome ?

Answer:
Metabolic syndrome has several causes that act together. You can control some of the causes, such as overweight and obesity, an inactive lifestyle, and insulin resistance.
                
You can't control other factors that may play a role in causing metabolic syndrome, such as growing older. Your risk for metabolic syndrome increases with age.
                
You also can't control genetics (ethnicity and family history), which may play a role in causing the condition. For example, genetics can increase your risk for insulin resistance, which can lead to metabolic syndrome.
                
People who have metabolic syndrome often have two other conditions: excessive blood clotting and constant, low-grade inflammation throughout the body. Researchers don't know whether these conditions cause metabolic syndrome or worsen it.
                
Researchers continue to study conditions that may play a role in metabolic syndrome, such as:
                
A fatty liver (excess triglycerides and other fats in the liver)
                
Polycystic ovarian syndrome (a tendency to develop cysts on the ovaries)
                
Gallstones
                
Breathing problems during sleep (such as sleep apnea)
Question:
Who is at risk for Metabolic Syndrome? ?

Answer:
People at greatest risk for metabolic syndrome have these underlying causes:
                
Abdominal obesity (a large waistline)
                
An inactive lifestyle
                
Insulin resistance
                
Some people are at risk for metabolic syndrome because they take medicines that cause weight gain or changes in blood pressure, blood cholesterol, and blood sugar levels. These medicines most often are used to treat inflammation, allergies, HIV, and depression and other types of mental illness.
                
Populations Affected
                
Some racial and ethnic groups in the United States are at higher risk for metabolic syndrome than others. Mexican Americans have the highest rate of metabolic syndrome, followed by whites and blacks.
                
Other groups at increased risk for metabolic syndrome include:
                
People who have a personal history of diabetes
                
People who have a sibling or parent who hasdiabetes
                
Women when compared with men
                
Women who have a personal history of polycystic ovarian syndrome (a tendency to develop cysts on the ovaries)
                
Heart Disease Risk
                
Metabolic syndrome increases your risk for coronary heart disease. Other risk factors, besides metabolic syndrome, also increase your risk for heart disease. For example, a high LDL (bad) cholesterol level and smoking are major risk factors for heart disease. For details about all of the risk factors for heart disease, go to the Coronary Heart Disease Risk Factors HealthTopic.
                
Even if you dont have metabolic syndrome, you should find out your short-term risk for heart disease. The National Cholesterol Education Program (NCEP) divides short-term heart disease risk into four categories. Your risk category depends on which risk factors you have and how many you have.
                
Your risk factors are used to calculate your 10-year risk of developing heart disease. The NCEP has an online calculator that you can use to estimate your 10-year risk of having a heart attack.
                
High risk: Youre in this category if you already have heart disease or diabetes, or if your 10-year risk score is more than 20 percent.
                
Moderately high risk: Youre in this category if you have two or more risk factors and your 10-year risk score is 10 percent to 20 percent.
                
Moderate risk: Youre in this category if you have two or more risk factors and your 10-year risk score is less than 10 percent.
                
Lower risk: Youre in this category if you have zero or one risk factor.
                
Even if your 10-year risk score isnt high, metabolic syndrome will increase your risk for coronary heart disease over time.
Question:
What are the symptoms of Metabolic Syndrome ?

Answer:
Metabolic syndrome is a group of risk factors that raises your risk for heart disease and other health problems, such as diabetes and stroke. These risk factors can increase your risk for health problems even if they're only moderately raised (borderline-high risk factors).
                
Most of the metabolic risk factors have no signs or symptoms, although a large waistline is a visible sign.
                
Some people may have symptoms of high blood sugar if diabetesespecially type 2 diabetesis present. Symptoms of high blood sugar often include increased thirst; increased urination, especially at night; fatigue (tiredness); and blurred vision.
                
High blood pressure usually has no signs or symptoms. However, some people in the early stages of high blood pressure may have dull headaches, dizzy spells, or more nosebleeds than usual.
Question:
How to diagnose Metabolic Syndrome ?

Answer:
Your doctor will diagnose metabolic syndrome based on the results of a physical exam and blood tests. You must have at least three of the five metabolic risk factors to be diagnosed with metabolic syndrome.
                
Metabolic Risk Factors
                
A Large Waistline
                
Having a large waistline means that you carry excess weight around your waist (abdominal obesity). This is also called having an "apple-shaped" figure. Your doctor will measure your waist to find out whether you have a large waistline.
                
A waist measurement of 35 inches or more for women or 40 inches or more for men is a metabolic risk factor. A large waistline means you're at increased risk for heart disease and other health problems.
                
A High Triglyceride Level
                
Triglycerides are a type of fat found in the blood. A triglyceride level of 150 mg/dL or higher (or being on medicine to treat high triglycerides) is a metabolic risk factor. (The mg/dL is milligrams per deciliterthe units used to measure triglycerides, cholesterol, and blood sugar.)
                
A Low HDL Cholesterol Level
                
HDL cholesterol sometimes is called "good" cholesterol. This is because it helps remove cholesterol from your arteries.
                
An HDL cholesterol level of less than 50 mg/dL for women and less than 40 mg/dL for men (or being on medicine to treat low HDL cholesterol) is a metabolic risk factor.
                
High Blood Pressure
                
A blood pressure of 130/85 mmHg or higher (or being on medicine to treat high blood pressure) is a metabolic risk factor. (The mmHg is millimeters of mercurythe units used to measure blood pressure.)
                
If only one of your two blood pressure numbers is high, you're still at risk for metabolic syndrome.
                
High Fasting Blood Sugar
                
A normal fasting blood sugar level is less than 100 mg/dL. A fasting blood sugar level between 100125 mg/dL is considered prediabetes. A fasting blood sugar level of 126 mg/dL or higher is considered diabetes.
                
A fasting blood sugar level of 100 mg/dL or higher (or being on medicine to treat high blood sugar) is a metabolic risk factor.
                
About 85 percent of people who have type 2 diabetesthe most common type of diabetesalso have metabolic syndrome. These people have a much higher risk for heart disease than the 15 percent of people who have type 2 diabetes without metabolic syndrome.
Question:
How to prevent Metabolic Syndrome ?

Answer:
Making heart-healthy lifestyle choices is the best way to prevent metabolic syndrome by:
                
Being physically active
                
Following a heart-healthy eating plan
                
Knowing your weight, waist measurement, and body mass index
                
Maintaining a healthy weight
                
Make sure to schedule routine doctor visits to keep track of your cholesterol, blood pressure, and blood sugar levels. Speak with your doctor about a blood test called a lipoprotein panel, which shows your levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.
