Arrhythmia: It is a problem associated with the rate of rhythm at which the heart beats. Generally, in this condition, the heart beats too fast, too slow or with an irregular rate. It can lead to severe heart damage. A cardiac arrhythmia occurs when there are abnormal electrical signals in the heart. When the heart beats too fast, it is known as tachycardia, and if it is too slow, it is called bradycardia. Treatment of arrhythmia includes drugs, medical procedures, implantable devices and sometimes surgery.
