Arrhythmia
About Arrhythmia
The term "arrhythmia" refers to any problem in the rate and/or rhythm of a person’s heartbeat. During an arrhythmia, changes in heart tissue and activity, or in the heart’s electrical impulses, may cause the heartbeat to be too fast, too slow or erratic. This is known as an irregular heartbeat.
