Electrophysiology and Arrhythmia Service

Electrophysiology and Arrhythmia Service team

The Johns Hopkins Electrophysiology Program was established in the early 1970s with the goal of using state-of-the-art technology, a multidisciplinary team, compassion and dedication to provide patients with timely and accurate diagnoses and therapies. With 15 electrophysiologists and arrhythmia specialists at six hospitals, nine outpatient clinics and two ambulatory surgery centers in the mid-Atlantic region, Johns Hopkins has one of the largest and most highly regarded arrhythmia programs in the nation. Our experts evaluate nearly 10,000 patients in the outpatient setting and perform more than 3,500 electrophysiology and device procedures each year.

The electrophysiology program has established itself as a world leader in multiple focus areas including:

  • Atrial fibrillation ablation with the latest technology, including pulsed field ablation
  • Diagnosis, management and ablation of supraventricular tachycardias
  • Ventricular tachycardia ablation, with expertise in coronary artery disease, arrhythmogenic right ventricular cardiomyopathy (ARVC), sarcoidosis and other infiltrative diseases
  • Arrhythmia management in congenital and inherited heart disease
  • Implantation of leadless devices, as well as lead management and extraction
  • Left atrial appendage closure procedures
  • Clinical and translational research in atrial fibrillation, inherited heart disease, ventricular tachycardia and ARVC

In the past year, we welcomed two new electrophysiologists, Nino Isakadze and Michael Powers, and launched our atrial fibrillation clinic.
