What is Arrhythmia?
An arrhythmia is an abnormal heart rhythm. The heartbeat is tightly controlled by the heart's own electrical system—it normally keeps the heart beating in a regular pattern between 60 and 100 times per minute. When the normal electrical system gets disrupted, arrhythmias can occur.
With an arrhythmia, the heartbeat can become too fast, too slow, or irregular. The heart pumps blood less effectively when this happens and this can cause symptoms. Some arrhythmias can lead to more serious medical problems. You should consult a doctor if you are experiencing symptoms of an arrhythmia.
