EPS

An EP study is a test that shows how electrical signals move in pathways through your heart. When the pathway is normal, your heart beat is regular. When these signals are abnormal, your heartbeat is irregular. An irregular heartbeat is called an arrhythmia. RFA is a procedure used to treat some types of arrhythmias.

An EP study uses one or more catheters (flexible tubes) that are moved through a vein into your heart. The catheters contain tiny sensors that measure how electric signals move through your heart. During RFA, a catheter is placed next to the heart cells that are creating the abnormal electrical signals. The tip of the catheter sends radiofrequency energy to destroy the abnormal cells in that area. This can bring the heart back to a normal rhythm.
