Electrical Cardioversion

For Atrial Fibrillation or Flutter

Sometimes the heart can go into an abnormal rhythm like atrial fibrillation or atrial flutter. These rhythms can cause very fast heart rates, low blood pressure, and may increase the risk of developing blood clots that can cause a stroke. Depending on your history and some of your risk factors, your doctor might suggest giving you an electric "shock" to help restore a normal heart rhythm. This procedure is called an Electrical Cardioversion, and it is usually done with some sedative or pain medications. It is not always successful, and the abnormal heart rhythm may return again in the future. In addition to effects from medication, complications can include things like causing a stroke, a dangerously fast or slow heart rhythm, decreased breathing, or very rarely death.*
