People with atrial fibrillation, ventricular arrhythmias or
supraventricular tachycardia are commonly treated with cardioversion.
This procedure restores normal heart rhythm. During cardioversion,
electrophysiologists place a patch on the front and back of the
patient’s chest and deliver an electric shock to the heart. The shock
interrupts the abnormal electrical rhythm and restores normal heart
rhythm. Following cardioversion, patients may be given medicine to
prevent blood clots and future arrhythmias.
