Answer

Cardioversion can have several adverse effects. It may induce dysrhythmias because of inadequate synchronization, with the shock occurring during the ST segment or T wave. Rarely, even a properly synchronized shock can produce VF. Postcardioversion dysrhythmias are generally transient and do not require treatment.
