Our Clinical Electrophysiology program at Lenox Hill Hospital and the Northwell Cardiovascular Institute drives innovation in catheter-based arrhythmia management through investigator-initiated research inspired directly from our experience in the electrophysiology laboratory. As pulsed field ablation has transformed atrial fibrillation treatment, our team has emerged as a national leader in characterizing intravascular hemolysis across PFA technologies. We are simultaneously advancing energy delivery optimization for PFA catheters, evaluating adjuvant lesion strategies for persistent atrial fibrillation, pioneering non-invasive 3D electroanatomic mapping and novel multipolar catheter techniques for complex ventricular arrhythmias.
