Clinical Interests

Nipavan Chiamvimonvat completed a two-year clinical cardiac arrhythmia fellowship at the University of Calgary and was also a research fellow at Johns Hopkins University from 1993 to 1997. Her clinical activities include attending for pacemaker and defibrillator clinics, coronary care unit service, and consult service. Chiamvimonvat's research goal is to understand the cellular and molecular mechanisms contributing to cardiac arrhythmias and sudden cardiac death in patients with cardiac hypertrophy and failure. She is working to develop a multidisciplinary research initiative in cardiovascular biology, which will include emphasis on fundamental mechanisms in cardiac arrhythmias and cardiac ion channelopathy.
