What is an arrhythmia?
A person with an arrhythmia has an abnormal heart rate or heart rhythm. An electrical impulse stimulates the muscle fibers in the heart to contract. Any abnormality or disturbance in the impulse can result in a cardiac arrhythmia.

How does the doctor treat an arrhythmia?
Treatment for an arrhythmia depends on the underlying cause. Measures may include the avoidance of stimulants that can accelerate the heart and medications that control rhythm. In some cases, a cardiac pacemaker may be required to control the heartbeat.
