Cardiac electrophysiology

After my medical education and training in Cambridge and London, England, I came to the US to do a year of Cardiovascular Research. I was offered directorship of the first coronary care unit at University of Massachusetts Medical Center. While there I continued my keen interest in cardiac arrhythmias, resulting in the development of the Cardiac Electrophysiology and Pacing Program developing the second Cardiac Electrophysiology and Pacing laboratory in New England in 1983. While there, we established the Clinical Pharmacokinetics of Amiodarone and were among the first to use this drug in the USA.

In 1989, I moved to St. Elizabeth's medical Center (an affiliate of Tufts School of Medicine) where I was instrumental in developing their Cardiac Electrophysiology and Pacing Program. I spent over 20 years there as Director and recently moved to the Cardiovascular Consultants of Cape Cod where I am now Director of Device Trials and Electrophysiology Network Development.

I have been instrumental in training more than 25 Cardiac Electrophysiologists. I have combined clinical care, teaching and education, clinic research and administration throughout my career. In 1990 I was made full Professor of Medicine at Tufts University School of Medicine.

I have participated in numerous clinical trials both multicenter, NIH-sponsored and single center, in the areas of antiarrhythmic agents/development, pacemaker and defibrillator trials which I continue to actively pursue. I enjoy teaching medical students, residents, and colleagues and have spent my entire career in Academic Clinic Cardiac Electrophysiology, Pacing and Defibrillation. In the process, I have developed a strong referral base and a very large clinical cardiac practice and following. I will continue my clinical practice, teaching Harvard Medical students, Residents and Fellows at BIDMC Research and remaining as academic as possible.

During the past 10 years I have been seeing and treating patients with cardiac arrhythmias in the Cape Cod area. This allows me to apply my interests in electrophysiology while caring for patients for whom a trip to Boston for this highly specialized care would be difficult if not impossible. And it allows me to spend more time on the Cape – the most beautiful place in the world!
