Abnormal Heartbeat (Arrhythmia)

What is an arrhythmia?

Normal hearts beat at a rate of approximately 60 to 100 times per minute. An abnormal rhythm or cardiac arrhythmias is the disturbance of the normal rhythms of a heartbeat. The rhythm can either be too fast, too slow or irregular.

What causes an arrhythmia?

An arrhythmia is caused by a problem with the electrical signals that tell your heart muscle when to contract. Other problems that arise from this condition include the heart's ability to properly pump blood from its upper or lower chambers. This can reduce blood flow to vital organs, leaves the blood stagnate, which may cause clots that can travel to other parts of the body, and cause blockage to the limbs, brain or heart.
