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.

Pulsed field ablation shows more positive data as treatment for AFib

Pulsed field ablation is one of the biggest technology trends in cardiac electrophysiology and may become a new standard of care in atrial fibrillation the coming years based on clinical data.
