Center for Heart Rhythm Disorders
The human heart beats approximately 100,000 times a day—about 35 million times a year. Each heartbeat begins with an electrical impulse within the heart's own electrical network, called the conduction system.
The electrical impulse of the conduction system starts in the atria, or upper chambers of the heart, and travels down to the ventricles, or lower chambers of the heart, to produce a heartbeat.
Heart rhythms disorders (also called arrhythmias or dysrhythmias) are problems with the conduction system that result in irregular heartbeats that are too fast (tachycardia), too slow (bradycardia), and/or irregular (extra or skipped beats). Heart rhythm disorders range from harmless to life-threatening. Read More
