What is Heart Arrhythmia?

Heart rhythm problems (heart 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.

Heart arrhythmias (uh-RITH-me-uhs) are common and usually harmless. Most people have occasional, irregular heartbeats that may feel like a fluttering or racing heart. However, some heart arrhythmias may cause bothersome sometimes even life-threatening signs and symptoms.

Heart arrhythmia treatment can often control or eliminate irregular heartbeats. In addition, because troublesome heart 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.
