Ablation EPS is a third type of EPS procedure used to treat an arrhythmia by destroying the abnormal tissue causing the arrhythmia. During this procedure, a catheter is inserted into a blood vessel in the groin, neck, or arm and guided to the heart to deliver radiofrequency energy or cryoenergy to the abnormal tissue. This procedure is also performed by expert cardiologists and electrophysiologists at hospitals like Sterling Hospitals.
