Diagnostic & Interventional Electrophysiology Studies
An electrophysiology (EP) study is a procedure in which special catheters containing multiple electrode wires are inserted into a vein or artery in the groin and guided to the heart, where they record the heart's electrical activity. These measurements are very helpful in diagnosing abnormally fast heart rhythms (tachycardias) or abnormally slow heart rhythms (bradycardias). The EP study can help the doctor pinpoint where the abnormal heart rhythms are coming from. The results from this study will help the doctor make recommendations about other types of treatments such as ablation to remove the abnormal rhythm, implantation of a pacemaker and/or defibrillator, or certain types of medications to control the abnormal heart rhythm (antiarrhythmic drugs).
