Dr. Zian H. Tseng is a cardiologist and electrophysiologist (a specialist in heart rhythm disorders). He is an expert in determining the risk of patients prone to sudden cardiac death (SCD) and ventricular arrhythmias, which can cause SCD. He also specializes in catheter ablation of complex arrhythmias (a procedure to destroy heart tissue causing abnormal rhythms), implanting defibrillators and resynchronizing heart devices. He has special expertise in performing these procedures for patients with congenital heart disease. He also helps develop new devices to treat heart rhythm disorders.
Tseng is the principal investigator for the POstmortem Systematic InvesTigation of Sudden Cardiac Death (POST SCD) study, a collaboration with the San Francisco Office of the Chief Medical Examiner that has been funded by the National Institutes of Health since 2010. The study's goal is to more accurately define SCD and determine its underlying causes, risk factors and genetics. He is also the principal investigator for the San Francisco POstmortem Systematic InvesTigation of Sudden Death in the Young (POST SDY) registry, which is funded by the Centers for Disease Control and Prevention, and works to more accurately define sudden death in pediatric populations. In addition, he is studying the risk of sudden death with the use of Tasers by law enforcement agencies.
A Bay Area native, Tseng completed undergraduate studies in molecular biology and biochemistry at the University of California, Berkeley and earned his medical degree at UCSF, where he also completed a year of graduate studies in biomedical sciences. He completed subspecialty training in internal medicine, cardiology and cardiac electrophysiology at UCSF.
