Electrophysiology

The cardiac subspecialty of electrophysiology (EP) diagnoses and treats arrhythmias. This includes use of pacemakers to treat bradycardia, implantable cardioverter defibrillators (ICD) for tachycardia, heart failure and patients at risk of sudden cardiac arrest, and cardiac ablation treatments to treat heart rhythm disorders.

The late-breaking U.S. multicenter admIRE clinical trial at the Heart Rhythm Society 2024 meeting, showed positive data on the long-term safety and effectiveness of the the Biosense Webster Varipulse pulsed field ablation (PFA) system in patients with paroxysmal atrial fibrillation. #HRS #HRS2024 #PFA
