K. (K. L.) L. Venkatachalam, M.D.

  1. Cardiac Electrophysiologist
  2. Cardiologist
  3. Internist

Dr. K.L.Venkatachalam is a clinical cardiac electrophysiologist with a special interest in atrial fibrillation treatment (invasive and non-invasive) and cardiac pacemaker and defibrillator implantation. He is also a Fellow of the Heart Rhythm Society.

Dr. Venkatachalam studies interventional approaches to managing rhythm disorders of the heart.

He combines his background in electronics engineering design and clinical cardiac electrophysiology to develop catheters, electronic hardware and software to enhance safety and efficacy in the electrophysiology lab during the evaluation and ablation of arrhythmias, specifically atrial fibrillation and ventricular tachycardia. He also investigates novel drug treatments for supraventricular tachycardia.

He also has a significant interest in novel approaches to teaching residents and fellows about cardiac rhythm recognition and management.
