Several studies on pulsed-field ablation are being highlighted at a heart rhythm conference, with some focusing on its use for atrial fibrillation and others on its application for scar-related ventricular tachycardia.

The conference in question may be either Heart Rhythm 2025 or a similarly named event in a different year, as the reporting outlets reference different years.
