Mechanisms of cardiac arrhythmias. Cardiac electrophysiology. Catheter ablation of arrhythmogenic foci.
My current research interests involve looking at mechanisms of supraventricular arrhythmias with respect to ablative therapy. In addition, we have initiated a cardiac genetic arrhythmic clinic to help define newer genes in causation of serious ventricular arrhythmias.
We are also studying the mechanism of atypical atrial flutter in humans. We have described the occurrence of double-wave reentry (1), and have extended these observations to describe an entity known as lower-loop reentry (2) which is also isthmus dependent. We have described a new type of atypical atrial flutter involving the left membranous septum and this work was presented at the North American Society of Pacing and Electrophysiology meetings (3).
