An abnormal heartbeat (arrhythmia) is any
variation in the normal heartbeat. Abnormal heartbeats occur when the heart has an
irregular heart rhythm, beats too fast (tachycardia), or beats too slow (bradycardia).
electrical system of the heart creates signals that trigger the heart to pump. These
electrical signals control the heart rate and rhythm. Normally, the heart beats in
a regular rhythm and at a rate that is appropriate for the work the body is doing.
An arrhythmia results from a problem in the electrical system of the heart.
arrhythmias are minor, causing only occasional abnormal heartbeats and requiring no
treatment. If an arrhythmia needs treatment, options may include medicines, an electrical
shock (cardioversion), a cardiac device such as a pacemaker, or ablation.
