Electrophysiology Study (EP Study) is a test where flexible wires are inserted into a vein, usually in the groin, and threaded into the heart. Electrodes at the end of the wires send information about the heart’s electrical activity. In this way, the EP study can map any abnormal electrical activity, identify the type of supraventricular tachycardia you have, and guide treatment including possibly ablating the problem area.
Often an EP study is done in conjunction with a tissue ablation.
