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.
Advances in medical technology have added new treatment methods to the procedures that doctors may use to try to control or eliminate arrhythmias. In addition, because troublesome arrhythmias are often made worse ? or are even caused ? by a weak or damaged heart, you may be able to reduce your arrhythmia risk by adopting a heart-healthy lifestyle
