Henry Hsia, MD

Clinical Professor

Dr. Hsia’s clinical and research interests have concentrated on the characterization of the electroanatomical substrate of ventricular arrhythmias, particularly in patients with nonischemic cardiomyopathy. His work focuses on identifying and defining various surrogate markers of the arrhythmia focus or circuit within the scar during a stable rhythm.

His research helped to develop new treatment strategies by deploying a substrate-based ablation for ventricular tachycardia, particularly in patients with ventricular arrhythmias that are unstable, with multiple morphologies, and not amendable to conventional mapping techniques.
