An electrical cardioversion, often referred to simply as a cardioversion, is a procedure used to treat an abnormal and rapid heart rhythm (also called a cardiac arrhythmia). The most commonly treated arrhythmia is atrial fibrillation. Another rhythm commonly treated with electrical cardioversion is atrial flutter. During a cardioversion procedure, an electrical "shock" is delivered to the chest to restore the heart rhythm to a normal pattern.

The team at Southwestern Cardiac Arrhythmia Institute in El Paso, TX along with Dr. Lookman Lawal have extensive experience diagnosing and treating congenital heart defects.
