Program Highlights

Our cardiac electrophysiology fellowship is a clinically-oriented, procedurally-heavy training program. We have two state-of-the-art electrophysiology labs that are concomitantly running, with a diversity of complex procedures. Fellows receive extensive training in:

  • Device implantation and management- including HIS and left bundle pacing
  • Implantable rhythm monitors
  • Use of the major mapping systems including Carto, Rhythmia and ESI
  • Radiofrequency ablation of atrial and ventricular arrhythmias
  • Epicardial access and ablation technique
  • Convergence procedure in collaboration with our cardiothoracic surgery colleagues
  • Laser lead extraction
  • Percutaneous left atrial appendage closure

Program structure

Clinical electrophysiology fellows spend their time primarily in the electrophysiology lab. There is a general cardiology fellow and nurse practitioners available for inpatient consultation at all times. The electrophysiology fellow oversees interesting/complex cases and pre-procedural planning along with the consultation team when needed.

Research Opportunity

Electrophysiology fellows have the opportunity to be involved in clinical prospective and respective research studies along with the electrophysiology faculty.

Under the supervision of Dr. Charles Antzelevitch, and in collaboration with his research team, the electrophysiology fellow has the opportunity to take part in basic science research within the Lankenau Institute for Medical Research facilities. The team is world renowned in the study of long QT and J-wave syndromes and has ongoing, NIH (R-01) funded studies on a weekly basis.
