Jay Nasir, M.D., specializes in cardiac electrophysiology, a life-saving treatment for arrhythmias of the heart.

Heart Expert Restores Rhythms

Solano County residents with heart arrhythmias used to have to travel out of the county to receive specialized care from a cardiac electrophysiologist. Now that service is just another one of the many advanced offerings provided by NorthBay Health Heart & Vascular, under the supervision of Javed (Jay) Nasir, M.D.

Dr. Nasir joined NorthBay in December, bringing an expertise in treating specific arrhythmias, such as atrial fibrillation and fibrillation with ablative procedures, according to Adam Mace, Director, NorthBay Health Heart & Vascular.

“NorthBay is the only health care organization in Solano County to offer this life-saving and life-improving specialty,” Adam noted. “We already have cardiovascular physicians who can do implants and treat arrhythmias, but Dr. Nasir’s expertise takes it to the next level.” 

Arrhythmias happen when abnormal cells disrupt the heart’s normal electrical signals. The condition can increase the risk of heart failure, stroke, blood clots and even sudden death.

“We’re a really good team doing some exciting things for the community, growing year after year. To offer a full, complementary cardiovascular program, we needed cardiac EP. It was the missing piece.”

Electrophysiologists are experts in diagnosis and treatment of these abnormal rhythms with medications, pacemakers, defibrillations, and with catheter ablation. Catheter ablation is when an electrophysiol­ogist guides a tiny catheter and identifies the area of disruptive cells. After deploying a carefully administered dose of radiofrequency energy, like microwave heat, the electrophysiologist can destroy that small part of the heart’s disruptive tissue and restore it to regular rhythm. 

Dr. Nasir comes to NorthBay from Mercy Medical Center in Redding, where he served as Director of Cardiac Electrophysiology since 2020. Prior to that, he was Director of the Device Clinic at David Grant Medical Center and Chief of its Cardiac Electrophysiology program. He retired from the U.S. Air Force as a major in 2020, after a 24-year career.

NorthBay has invested in special equipment for his practice, including a cardiac mapping system, an ICE (Intracardiac Echo machine); a Claris recording system and a generator.

In the past, NorthBay physicians referred about 140 cases a year out of county, but now they can receive treatment close to home.

According to Adam, the Heart & Vascular team came together during the pandemic and brainstormed ways to grow. 

Meet Cardiac Electrophysiologist (Javed) Jay Nasir, M.D. 

Coming to NorthBay Health to establish Solano County’s only electrophysiology program offered Jay Nasir, M.D., a professional opportunity to create a program from the ground up, while reuniting with long-time Air Force colleagues. 

“This is an opportunity for me to work again with my former associates from David Grant Medical Center. Shea (Pribyl, D.O.) has been urging me to ‘get the band back together,’ so it’s a homecoming for me. We have a great group of cardiologists here at NorthBay.”

Dr. Nasir has long been fascinated with the technology of electrophysiology, but explaining what he does for a living elicits a different reaction from his triplet sons.

“They think my work is more along the lines of video gaming. They get that from when I’ve shown them images of the moment when an ablation resets the heart’s rhythm,” he said.

Dr. Nasir obtained his bachelor’s degree in chemistry from Louisiana State University, and his doctorate of Medicine from the Uniformed Services University of the Health Sciences in Maryland. He did his residency in Internal Medicine, and his fellowship in Cardiovascular Disease, at Wilford Hall Medical Center in San Antonio. He earned his Clinical Cardiac Electrophysiology fellowship from Stanford University.
