Laurence M. Epstein, MD
Professor of Cardiology at the Zucker School of Medicine at Hofstra/Northwell
Professor, Bioelectric Medicine, Feinstein Institute of Medical Research
System Director of Electrophysiology, Northwell Health, New York.
Laurence Epstein, MD is the System Director of Electrophysiology for Northwell Health, Professor of Cardiology at the Zucker School of Medicine at Hofstra/Northwell and Professor, Bioelectric Medicine, Feinstein Institute of Medical Research. Previously Dr. Epstein was the Chief of the Arrhythmia Service of Brigham and Women’s Hospital and a Professor of Medicine at Harvard Medical School. Dr. Epstein’s career has spanned the era of modern clinical cardiac electrophysiology, and he has played a critical role in the development of many of its important advances. His research interests have included new ablative techniques, the development and use of intracardiac echocardiography, physiologic pacing, leadless pacing and new techniques for removing chronic transvenous leads.
Dr. Epstein received his BA in Biology from Carleton College in 1980 and a medical degree from the University of Chicago in 1985. This was followed by an internal medicine residency and a research fellowship in cardiac electrophysiology at University of California San Francisco Medical Center (UCSF). He completed his Cardiology fellowship at the Hospital of the University of Pennsylvania, and then a clinical electrophysiology fellowship and at UCSF. In 1992 he joined the faculty of UCSF and in 1994 moved to Boston to help Dr. Mark Josephson build an electrophysiology program at the Beth Israel Hospital. In 2000 Dr. Epstein became the Chief of the Arrhythmia Service of Brigham and Women’s Hospital and in 2014 was promoted to Professor of Medicine at Harvard Medical School. In 2017 he was recruited to be the first System Director of Electrophysiology for Northwell Health, the largest healthcare system in New York.
Much of invasive cardiac electrophysiology did not exist as recently 30 years ago. Dr. Epstein has had the opportunity to contribute to and help shape the field as it has evolved. He was involved in the development of a variety of catheter-based treatments for cardiac arrhythmias including the development of, and the first to report a curative procedure to treat AVNRT; the treatment for inappropriate sinus tachycardia; a transseptal approach for left atrial catheter ablation, and the use of intracardiac echocardiography (ICE) to guide ablation procedures. Dr. Epstein is considered one of the world experts performing transvenous lead extraction and has brought this skill to several countries around the world (for example he performed the first ever laser extraction in China). In his current role as system director of a 23-hospital network, Dr. Epstein is defining and instituting how to best manage arrhythmias across a large population and identifying barriers to care such as health care disparities. This includes novel approaches to patient monitoring and the use of large data sets and AI predictive modeling to move from treatment to prevention of disease.
Dr. Epstein is the author of over 200 peer-reviewed publications, multiple guidance documents and book chapters. He has trained over 100 fellows, many of the current and coming generation of cardiac electrophysiologists, including past presidents of the Heart Rhythm Society, EP program directors and Chiefs of Cardiology. Dr. Epstein is a sought-after speaker and educator and has been invited to give hundreds of lectured across the country and around the world.

I have always been driven by a passion for learning and a commitment to education. My journey began during residency, where I was honored as the Resident of the Year and assumed leadership roles as Chief Resident and Chief Fellow in Cardiology.
My Electrophysiology fellowship at the Beth Israel Deaconess Medical Center provided invaluable training under the tutelage of Mark Josephson, Alfred Buxton, and Peter Zimetbaum. I translated this advanced knowledge after returning to Northwell into teaching, earning the Teacher of the Year award in my first year as an attending and actively contributing to medical school EKG instruction.
Over the years, I established myself as a high-volume EP operator and fostered strong community relationships with referring physicians. My dedication to academic advancement continued with research mentorship for Cardiology fellows and IM residents, resulting in consistent presentations at national meetings and numerous peer-reviewed publications,including a collaborative book chapter.
I was honored with the opportunity to become Director of the Electrophysiology service at LIJ hospital in 2022. In this role, we have successfully enhanced efficiency and driven volume growth. I have also developed my leadership skills to build a unified and efficient department for the satisfaction of our patients.
My future goals involve expanding my national and international presence through presentations at ACC and HRS, while continuing my passion for research and education. I believe it is crucial to continue the pursuit of the perpetual learner and enhance my professional development. I eagerly anticipate the opportunities ahead to innovate and contribute to the field.
