Thomas A. Dewland


Cardiologist and electrophysiologist
Arrhythmia researcher and trail runner

Dr. Thomas A. Dewland is a cardiologist with particular expertise in electrophysiology, the study of the heart's electrical activity. He cares for patients with arrhythmias (heart rhythm problems) in both the clinic and the hospital. Among other treatments, he performs catheter ablation (in which a flexible tube called a catheter is threaded through a blood vessel to reach the heart and destroy the tissue causing an arrhythmia), pacemaker implantation, implantable cardioverter defibrillator placement and left atrial appendage closure (sealing the heart sac where blood clots form to help prevent stroke in patients with the heart rate irregularity called atrial fibrillation).

In research, Dewland focuses on atrial fibrillation epidemiology (the study of which populations are affected by certain diseases and why). His goal is to identify ways to prevent atrial fibrillation before it occurs.

Dewland earned his medical degree at the Yale School of Medicine. At UCSF, he completed a residency in internal medicine, a fellowship in cardiology and a fellowship in cardiac electrophysiology, as well as the Advanced Training in Clinical Research Certificate Program.

Outside of work, Dewland enjoys spending time with his wife – a pediatrician at UCSF – and their two children.

Cardiac arrhythmia care can be complex, but good patient care is not. I listen to my patients, and together we choose an effective treatment plan.
