The electrophysiology (EP) study is an invasive procedure used to identify heart rhythm problems. It can help assess any underlying rhythm-related cause of symptoms like palpitations or syncope. Performed by skilled electrophysiologists in specialized EP labs, this study can help identify arrhythmias and the need for devices like pacemakers or defibrillators. In some cases, catheter ablation may be performed simultaneously during the procedure to treat an abnormal rhythm. During the procedure, patients are continuously monitored for any adverse effects to ensure complete safety. Understanding the risks, including bleeding and clot formation, benefits, and alternatives, to this procedure is important for patients beforehand.
