Dr. Schoenfeld specializes in diagnosing and treating cardiac arrhythmias through electrophysiology studies, ablation, and device implantation (pacemakers, defibrillators). His research focuses on advancing device therapy and remote monitoring, with significant contributions to ACC/AHA/HRS clinical guidelines for managing rhythm disturbances. He actively engages in healthcare policy through FDA and CMS advisory roles.

Recent publications highlight his work on urgent arrhythmia protocols, device complications, and guideline development. His clinical trials have shaped advancements in implantable cardioverter-defibrillator technology and catheter ablation over three decades.

Scientific awards include Fellowships from Heart Rhythm Society, American Heart Association, and Yale-based clinical leadership recognition. He serves on the AMA’s RUC committee and reviews for major journals like the American Journal of Cardiology.
