Your doctor is recommending a procedure called cardioversion. If you have been experiencing abnormal heartbeats, this procedure will help return your abnormal heartbeat to normal.
Problems in your heart's electrical pathways can be caused by disease, heart damage, or a condition that you were born with. Whatever the cause, the result is abnormal heartbeats, and not enough blood and oxygen pumped to your body and brain.
When your heart's electrical system is not working right, you may experience symptoms such as feeling dizzy, lightheaded, tired, confused, or short of breath. You may also have had fainting spells, blurred vision, or palpitations, which is a pounding feeling in your chest.
One option to correct the abnormal electrical pattern and hopefully relieve your symptoms is pharmaceutical cardioversion, to put it simply, correcting your abnormal heartbeats with medication.
