Toward the beginning of fellowship, Cardiology fellows rotate on the cardiac electrophysiology service for a total of two months. During this period of time, they are exposed to the medical management of a wide variety of cardiac arrhythmias, in both the in-patient and out-patient clinical settings. A large component of the rotations involves time spent in the EP Lab. Corewell Health Dearborn Hospital has a very busy cardiac electrophysiology service, performing more than 70 EP studies, more than 350 device implants (pacemaker and ICD) and almost 400 intra-cardiac ablations (atrial fibrillation, atrial flutter, SVT) annually.
