Elective Cardioversion

Elective cardioversion is a procedure that converts certain types of abnormal heart rhythms (arrhythmias) to normal rhythms. There are two types of electrical cardioversion, internal and external. External cardioversion may be performed in an emergency situation (e.g., with a defibrillator) or in a non-emergency situation.

The most common type of non-emergency external cardioversion uses mild electrical shocks that are carefully timed to stop an arrhythmia and restore a normal heartbeat. In addition, cardioversion may also be accomplished with medications.
