Electrophysiology is the fastest-growing subspecialty across the nation, hospital leaders told Becker’s, thanks to a number of factors that are changing the field.
Electrophysiology is a unique specialty within cardiology due to how many areas of patient care it addresses. Electrophysiologists treat a range of conditions across all ages, and have seen a dramatic increase in the volume of cases in recent years, experts told Becker’s. Although many hospital leaders say electrophysiology is one of the fastest-growing specialties, there is no nationally available data to support this as databases like the Bureau of Labor Statistics does not track this subspecialty.
For example, when Paari Dominic, MD, director of electrophysiology at Iowa City, Iowa-based UI Health, stepped into his role in 2023, there were three full-time EPs on staff and they performed 900 procedures a year. In 2026, they have nine EPs on staff — with three more joining the team in coming months — and perform more than 3,200 a year. That’s about a 300% increase in volume in three years, and doesn’t include outreach procedures, Dr. Dominic said. Even with the growing team, patients still have a 60 to 90-day waiting period to be seen and scheduled for their procedures.
“Part of what drove the growth at our main center wasn’t purely new patients — we simply didn’t have enough manpower before, so we had longer wait times and patients were backing up,” Dr. Dominic said. “Addressing that staffing gap is what allowed us to absorb all that volume.”
But what’s behind EPs growth in recent years? There are several factors.
What’s driving EPs growth
The aging population has been pushing the growth of electrophysiology by increasing the number of atrial fibrillation, heart failure and other complex rhythm-disorder cases. Traditionally, older patients were not a good candidate for many procedures like ablation, but new technology like pulsed field ablation have changed that. This new non-thermal ablation technique has lower risk of damage to heart tissue and other structures around the heart, making it ideal for older patients, Usha Tedrow, MD, director of fellowship and the Clinical Cardiac EP Program at Boston-based Mass General Brigham’s Brigham & Women’s, told Becker’s. This method has taken over the field in the last few years and helped increase the volume of procedures.
Updated clinical guidelines encouraging earlier intervention for many arrhythmias has also increased procedural volumes, Olivia Fleming MSN, RN, corporate vice president of cardiovascular service line at New Orleans-based LCMC Health, told Becker’s.
Electrophysiology is also seeing growth in leadless pacing, left atrial appendage occlusion and combined procedures, Jessica Hennessey, MD, PhD, a cardiac electrophysiologist and assistant professor of medicine at New York City-based Columbia University Vagelos College of Physicians and Surgeons, told Becker’s. This has allowed for growth in all areas of EP care.
In pediatrics, electrophysiologists are primarily seeing young patients with arrhythmia, tachycardia, genetic arrhythmias and cardiomyopathies that carry a predisposition to arrhythmia or risk sudden cardiac death, Jeffrey Robinson, MD, medical director of the pediatric cardiac electrophysiology and cardiology at Omaha-based Children’s Nebraska, told Becker’s.
At the Becker’s 32nd Annual Meeting: The Business and Operations of ASCs, taking place October 29-31 in Chicago, ASC leaders, surgeons and healthcare executives will explore strategies to drive growth, enhance operational performance, navigate reimbursement challenges and prepare for the future of ambulatory surgery.
