There are factors that predispose you to AF. Knowing these predisposing factors can help you to manage your AF. While some of these risk factors cannot be controlled, knowing what they are can help you to prepare for them, and will help when coming up with a management plan with your doctor. They include: Increasing age. Stroke and heart attack affect people of all ages, but the risk increases as you get older. Gender. Men more commonly develop medical conditions caused by AF. Heredity. People whose close blood relations have had a stroke have a higher risk of stroke, heart diseases, and AF. History of heart problems. If you have previously had a stroke or heart attack, your chances of having AF or other heart issues increases. Irregular heart rhythms due to AF can cause pooling of blood in the heart, which can lead to the formation of clots. These clots are at risk of being dislodged and traveling to the brain, where they can block blood flow and cause a stroke. You may also suffer from heart failure due to AF, because it causes the heart to beat irregularly. Over time, the heart muscle can become weak and this can result in poor circulation of blood throughout the body and eventual heart failure. When you have AF, your doctor may choose to routinely monitor your condition through a variety of tests that will provide a clearer picture or you condition. These tests may include: ECG, a diagnostic test for atrial fibrillation. Your doctor will be able to visualize irregularities in your heartbeat and interpret new and ongoing issues with your heart. Lab test for thyroid stimulating hormone (TSH), because elevated levels can cause your heart rate to rise. Lab tests for electrolytes such as potassium, sodium, magnesium, and calcium, which work for the proper functioning and timing or your heart muscle. Imbalances can affect your heart negatively. CBC or PT/INR, which check for the quality of your blood composition which affect your heart's ability to pump blood. Imaging, such as a chest X-ray, if cardiopulmonary disease is suspected. This can allow the doctor to actually see what is physically wrong or damaged in your heart.

summary: Be aware of the challenges. Understand the side effects. Get diagnostic test.

There are many papers for which no historical context is needed, but if historical context can help clarify things to the reader, a historical review introduction can be very helpful. These introductions are usually used for papers written about a historical time period or topic, a historical critique of a piece of literature, or a long-standing problem that people throughout the ages have tried to address. Outline or review a few key historical facts that offer the reader any essential information he or she might need in order to understand the topic of the paper. These pieces of information should not only provide context about the topic, but should also indirectly present the general topic itself. In doing this, you will demonstrate the the reader how your topic fits into the historical account you present in your introduction. The information provided thus far will be fairly general, so you need to focus the end of your paragraph on a single thesis statement that you will use to define the rest of your paper. A thesis statement is a single sentence that defines a specific point or idea about a broader topic that your entire paper is built around. With this type of introduction, your thesis statement should cause the reader to view the historical facts you just presented in a specific light or through a specific lens. In effect, your thesis statement should tell the reader why the facts you presented before it are important to keep in mind.

summary: Determine if a historical review could be helpful. Provide factual and historical context about the the topic. Narrow your thoughts down to a thesis statement.

Remove some packages by pulling the plastic away at any spot that is labeled "pull here". Open packages without this feature by simply cutting them with a good pair of scissors. Keep in mind many Shirataki packages will have liquid in them. Don't worry about any smell the noodles might have. Rinsing noodles for 2-3 minutes will remove any residue from the manufacturing process. Use cold water when rinsing. Use a strainer for best results. Rinse the noodles thoroughly. Place a pot of water on your stove top. Turn the burner on underneath it to start raising the temperature of the water. Keep watch over the water to prevent it from boiling over. Turn the heat down if the water is boiling too strongly. Boil the noodles for 2 or 3 minutes. Try to get the noodles soft or otherwise at your preferred level of firmness. Boiling noodles too long will result in rubbery noodles. Don't boil too long as the water will evaporate, resulting in burnt noodles. Grab a strainer and put it in your sink. Pick up the pot with the water and noodles. Bring the pot over to the strainer and slowly pour the water and noodles into the strainer. Dump the noodles out of the strainer and back into your pot. Pour the water and noodles out slowly into the strainer. Be careful! Your water will be hot and can cause burns and injury.
summary: Open the packaging. Rinse the Shirataki noodles. Prepare water for boiling. Add noodles to boiling water. Strain the water from the noodles.
