There have been several advances in electrophysiology (EP) technologies this past year, many of which were highlighted during the Heart Rhythm Society (HRS). These advances included a leadless pacemaker, new data on contact force sensing ablation catheters, a new electromapping system entering the market and new techniques to map and ablate atrial fibrillation (AF), said Jagmeet Singh, M.D., Ph.D., director, resynchronization and advanced cardiac therapeutics program at the new Mass General Institute for Heart, Vascular and Stroke Care.
