In one sentence, describe what the following article is about: When the heart does not beat properly, it does not pump blood effectively all over the body, especially to the organs that are highly dependent on blood supply such as the brain, lungs and kidneys. Inadequate blood supply may cause these organs to become damaged in the long run and eventually shut down. According to the Centers of Disease Control and Prevention, an estimated 600,000 people die from sudden cardiac death per year and up to 50% or patients have sudden death as the first manifestation of cardiac disease. Normally, the heart fires impulses that start from the sinoatrial node. However some conditions, such as blocks in the conduction pathway, predispose the heart to fire in abnormal rates that cause irregular beats. These irregular beats may decrease blood supply to the vital organs. This can lead to symptoms such as heart palpitations, fatigue, slow heart beats, chest pain, loss of consciousness, dizziness, lightheadedness, mental confusion, fainting, shortness of breath, and sudden death. Family history is the most significant risk factor for arrhythmia. Figure out if an immediate relative has heart disease and find out what age he was when he discovered the arrhythmia. This can make a difference arrhythmia in an 80-year-old is most likely not genetic, but an arrhythmia in a 20-year-old is much more likely. Look for conditions such as a heart attack, angina, angioplasty, or a blocked artery. These conditions are genetic and cannot be changed. Genetics plays the most important role in how you should manage yourself because these risk factors are ones that you cannot change. However, you can make sure you follow a healthy lifestyle that reduces any additional risk of arrhythmia over time. High blood pressure can put you at risk for arrhythmia. To keep a watch on your blood pressure, check your blood pressure often. You can get free readings from machines found at many pharmacies, grocery stores, or general stores. If you systolic blood pressure, which is the top number, is 140 or higher, you need to change your lifestyle, such as reduced sodium diet weight loss and close follow up. If you have a family history of coronary artery disease, you most likely will need medication and lifestyles changes to help reduce it. There are a few other conditions that can cause arrhythmia. Overactive and underactive thyroids can cause arrhythmia. Individuals with obstructive sleep apnea may suffer from some for of arrhythmia as well. You may also suffer an arrhythmia if you have an electrolyte imbalance in your blood. Some of these conditions can be treated in other ways, so ask your doctor about treating the underlying condition that puts you at risk of arrhythmia.
Summary: Know what arrhythmia means. Recognize the signs and symptoms of arrhythmia. Research your family history. Keep a check on your blood pressure. Watch out for other risk factors.

In one sentence, describe what the following article is about: You want the chair to remain firmly in one place. Your feet should be planted on the floor, with your knees bent at ninety degrees. Make sure the chair is not wobbly, and doesn't rotate or have wheels (e.g. an office chair) If you are at the gym, you can sit on a weightlifting bench. The exercise band should be placed behind your knees, on top of your clothing. The band should be tight enough so that it is challenging to pull your knees apart, but not so hard that you cannot perform the exercise. Alternatively, you can also create resistance using your hands. Simply make a fist with both hands and place each hand on the outside of each knee. For example, your left hand will be on the outside of your left knee, and the right hand will be on the outside of your right knee. Use the strength of your arms as resistance. Take a breath in, and as you exhale, begin the exercise. try to push your knees apart, against the resistance bands for four seconds. Then, exhale as you release. Keep the muscles in your abdomen contracted while you do this exercise to keep your spine protected. Don't hold your breath as you perform the exercise, as this may make you dizzy. You should try to press against the band so that you feel the outer muscles of your thigh contracting. It is not necessary to spread your legs as wide as they will go. If it is possible for you to do this, you might need to try a tighter resistance band. You should try to do three sets of 15 repetitions. This means that you will repeat the exercise 15 times, take a short break of a minute or so, and then repeat for two more sets of 15. You should aim to do this exercise three to five times per week. If you feel that this is too hard for you, then do as many as you can, and work your way up. As you get stronger, you can move to a tighter resistance band.
Summary:
Sit in a chair with your knees bent. Place an exercise band around your thighs. Press your knees outward. Repeat the exercise.
