Cardioversion is a medical procedure to treat heart arrhythmias and restore a normal heart rhythm. There are 2 different types of cardioversion:

Direct current cardioversion is done by sending an electronic shock to your heart through patches or paddles placed on the chest to quickly restore a normal heart rhythm. Sedation or general anesthesia will be given prior to direct current cardioversion. In most instances, patients can go home the same day as their procedure.

Medical cardioversion is done by giving an anti-arrhythmic medication either by mouth or in an IV to restore a normal heart rhythm. The effect of these medications can take a few hours to work.
