Cardioversion

Cardioversion is a medical procedure performed to restore a normal heart rhythm for people who have certain types of abnormal heartbeats (arrhythmias). Cardioversion is most often performed by sending electric shocks to your heart through electrodes placed on your chest. Rarely, your doctor may perform cardioversion using only medications to restore your heart's rhythm.

Risks
Complications of electric cardioversion are rare, and doctors can take steps to reduce your risk. Major risks of cardioversion include: Dislodged blood clots. Some people who have arrhythmias have blood clots in their hearts. Electric cardioversion can cause these blood clots to move to other parts of your body, which can cause life-threatening complications, such as a stroke or a blood clot travelling to your lungs (pulmonary embolism). Your doctor will check for blood clots in your heart before cardioversion and prescribe blood-thinning medications if blood clots are found.; Abnormal heart rhythm. In rare cases, some people who undergo cardioversion end up with other heart rhythm problems during or after their procedure. This is a rare complication. If it happens, it usually shows up only minutes after your procedure, so your doctor can give you medications or additional shocks to correct the problem.; Skin burns. Rarely, some people have minor burns on their skin where their electrodes were placed.

What you can expect
During the procedure A nurse or technician will place several large patches called electrodes on your chest. The electrodes will be connected to a cardioversion machine (defibrillator) using wires. The defibrillator will record your heart rhythm throughout the procedure, and will deliver shocks to your heart to restore a normal heart rhythm. This machine can also pace your heart if it beats too slowly after cardioversion.

Why it's done
Cardioversion can correct a heartbeat that's too fast (tachycardia) or irregular (fibrillation). Cardioversion is usually used to treat people who have atrial fibrillation or atrial flutter, conditions in which the electrical signals that cause your heart to beat in a regular rate and rhythm don't properly travel through the upper chambers of your heart.
