Overview
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.
Dr. Dewland is highly rated in 33 conditions, according to our data. His clinical expertise encompasses Atrial Fibrillation, Arrhythmias, Atrioventricular Nodal Reentrant Tachycardia (AVNRT), Cardiac Ablation, and Pacemaker Implantation.
Dr. Dewland is board certified in American Board Of Internal Medicine, Clinical Cardiac Electrophysiology. He is actively involved in clinical research, co-authoring 110 peer reviewed articles and participating in 2 clinical trials. Dr. Dewland is currently accepting new patients.

Providers who actively participate in clinical research are generally at the forefront of the fields and aware of the most up-to-date advances in treatments for their patients.
2 Clinical Trials
Asian Heart And Vascular Center
Dr. Henry H. Hsia is a cardiologist and electrophysiologist in the Cardiac Electrophysiology and Arrhythmia Service. He performs catheter ablation to treat complex arrhythmias, or irregular heartbeats, particularly ventricular tachycardia. In his research, Hsia explores new mapping techniques for identifying unstable, life-threatening heart rhythms. Hsia earned a medical degree at Tufts University School of Medicine. He completed an internal medicine residency at Michigan Medicine, the medical system of the University of Michigan, followed by a cardiology fellowship at the University of Texas Southwestern Medical Center. He completed training in cardiac electrophysiology at the Hospital of the University of Pennsylvania. Before joining UCSF, Hsia worked at the University of Pennsylvania, Temple University and Stanford University. Hsia is an avid scuba diver and a certified diving medical officer. Dr. Hsia is highly rated in 17 conditions, according to our data. His clinical expertise encompasses Arrhythmias, Ventricular Tachycardia, Paroxysmal Supraventricular Tachycardia (PSVT), Cardiac Ablation, and Pacemaker Implantation. Dr. Hsia is board certified in American Board Of Internal Medicine, Clinical Cardiac Electrophysiology and American Board Of Internal Medicine, Internal Medicine. Dr. Hsia is currently accepting new patients.
