DefinitionBy Mayo Clinic staff
Heart rhythm problems (heart arrhythmias) occur when the electrical impulses in your heart that coordinate your heartbeats don't work properly, causing your heart to beat too fast, too slow or irregularly.
Heart arrhythmias (uh-RITH-me-uhs) may feel like a fluttering or racing heart, and they're often harmless. 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.
