Zian Tseng, MD

Professor In Residence
Medicine

Zian H. Tseng, M.D., M.A.S., a cardiologist and a cardiac electrophysiologist, joined the faculty in 2004, bringing expertise in risk stratification of patients prone to sudden death and ventricular arrhythmias. Dr. Tseng, a Bay Area native, is an alumnus of the UCSF School of Medicine, where he also completed a year of graduate studies in Biomedical Sciences and a Master's in Advanced Studies in Clinical Research. He completed his clinical training in internal medicine, cardiology, and cardiac electrophysiology at UCSF.

CLINICAL INTERESTS:
1) Treatment of complex supraventricular arrhythmias, including catheter ablation of atrial fibrillation and left atrial tachycardias occurring after atrial fibrillation ablation
2) Treatment and catheter ablation of ventricular tachycardia, including epicardial mapping and ablation
3) Treatment, risk stratification, and catheter ablation of arrhythmias in adult patients with congenital heart disease
4) Risk stratification and treatment of patients with high risk genetic arrhythmia syndromes
5) Implantation of intracardiac devices for treatment of heart failure (resynchronization) and risk of sudden cardiac death (defibrillators)
6) Application of new device technologies, such as performing percutaneous epicardial left atrial appendage (LAA) ligation

RESEARCH INTERESTS:
1) Principal Investigator for the POstmortem Systematic InvesTigation of Sudden Cardiac Death (POST SCD) Study, a collaboration with Dr. Ellen Moffatt in the San Francisco Office of the Chief Medical Examiner to more accurately define SCD, arrhythmic death, and its epidemiology and risk factors, funded by the NIH/NHLBI since 2010
2) Principal Investigator for the San Francisco POstmortem Systematic InvesTigation of Sudden Death Young (POST SDY) Study, to more accurately define sudden death in pediatric populations, funded by the CDC since 2015
3) Genetic epidemiology, novel molecular mechanisms, and risk factors for sudden cardiac arrest
4) Principal Investigator for NIH/NHLBI-funded HIV POST SCD Study: SCD and ventricular arrhythmias in the setting of HIV disease
5) Sudden neurologic death
6) Sudden death risk and public/health policy for use of Tasers (electrical conductive devices) by law enforcement agencies
