In this episode, I sit down with Dr. Jakrin “Joe” Kewcharoen, a Clinical Cardiac Electrophysiology fellow at UCSF to explore the journey of becoming a heart rhythm specialist and the important role fellows play in patient care at academic medical centers.

Dr. Kewcharoen shares his unique path from Thailand to the United States and explains how international medical graduates navigate the U.S. training system while pursuing highly competitive specialties like cardiology and electrophysiology.

The conversation also provides an inside look at how electrophysiology fellows work alongside attending physicians, nurse practitioners, nurses, and the broader care team in the EP lab. Fellows are already trained cardiologists who perform procedures, evaluate patients, and continue developing advanced procedural skills under expert supervision.

Dr. Kewcharoen also discusses the rapidly evolving field of electrophysiology, including new technologies that are transforming arrhythmia care and the complex puzzle-solving involved in treating ventricular tachycardia.

About the Guest

Dr. Jakrin “Joe” Kewcharoen

Dr. Kewcharoen graduated from Chulalongkorn University in Thailand in 2017 and moved to the United States in 2018 to pursue postgraduate medical training.

He completed his Internal Medicine residency at the University of Hawai‘i, followed by a Cardiovascular Disease Fellowship at Loma Linda University. He is currently completing a Clinical Cardiac Electrophysiology Fellowship at UCSF.

Dr. Kewcharoen has been highly active in academic research, with over 100 peer-reviewed publications during his medical training. His research focuses on electrophysiology procedural outcomes, sudden cardiac death in the community, and inherited arrhythmia syndromes such as Brugada syndrome, a genetic disorder associated with life-threatening arrhythmias.

At UCSF, he is currently involved in several research projects examining sudden cardiac death using a unique autopsy-based cohort, helping researchers better understand the cardiac and non-cardiac causes of sudden death.

Outside of medicine, Dr. Kewcharoen enjoys weightlifting, basketball, playing guitar, and board games.

What is Brugada Syndrome?

Brugada syndrome is an inherited condition that predisposes individuals to ventricular arrhythmias and sudden cardiac arrest, often diagnosed through characteristic ECG patterns.
