Dr. Krishnan’s career in Electrophysiology began with the legendary Dr. Gordon Moe, regarded as the father of Cardiac Electrophysiology at the Masonic Medical Research Laboratory in Utica NY while he was still a medical student. Working with Dr. Charles Antzelevitch, he described a novel mechanism of reentry called "phase 2 reentry" that is thought to underlie the development of arrhythmias in patients with idiopathic ventricular fibrillation, specifically the Brugada syndrome. Phase 2 reentry also defines the mechanism by which certain antiarrhythmic drugs cause arrhythmias. His research efforts also provide an explanation for the ST segment abnormalities in patients with the Brugada syndrome.

His current clinical interests relate to catheter ablation of arrhythmias (especially atrial fibrillation) and over the past several years have also included biomedical innovations on various cardiology procedures. In 2010, he described a novel cardiac structure termed the left atrial septal pouch. This structure can be a source of strokes in some patients.
