CLINICAL INTERESTS: Dr. Lee is a Cardiologist and a Cardiac Electrophysiologist. His main clinical interests include conduction disorders, arrhythmias, catheter ablation, implantable devices (including pacemakers, defibrillators and biventricular defibrillators), lead extraction, atrial fibrillation, atrial flutter, supraventricular tachycardias, ventricular tachycardias, and sudden death.


RESEARCH INTERESTS: Dr. Lee has a Masters Degree in Clinical Research. He had done research on arrhythmias after organ transplant, the effects of the TASER on the heart, ICD complications, the effects of second hand smoking on heart rhythm, and risk stratficiation after myocardial infarction. Currently, he is the Co-PI of the VEST study, a multi-center, international randomized study to determine whether a wearable defibrillator vest can reduce the big early sudden death rate post-MI.
