Heart Palpitation is medically termed as Arrhythmias. Heart rhythm problems (arrhythmias) occur when the electrical impulses in your heart that coordinate your heartbeats don't function properly, causing your heart to beat too fast, too slow or irregularly. Arrhythmias are common and usually harmless. Most people have occasional, irregular heartbeats that may feel like a skipped, fluttering or racing heart. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms. If you've received a diagnosis of arrhythmia, treatment may or may not be necessary. Usually, it's required only if the arrhythmia is causing significant symptoms or if it's putting you at risk of a more serious arrhythmia or arrhythmia complication. Many arrhythmias can be blamed on underlying heart disease, so your doctor may advise that, in addition to other treatments, you make lifestyle changes that will keep your heart as healthy as possible. For instance, he or she may advise that you: * Eat heart-healthy foods * Increase your physical activity * Quit smoking * Cut back on caffeine and alcohol * Find ways to reduce the amount of stress in your life * Avoid stimulant medications, such as medications found in over-the-counter treatments for colds and nasal congestion-
