Jag Singh, MD, DPhil, is the Associate Chief of the Cardiology Division and the Roman W. DeSanctis Endowed Chair in Cardiology. He is a Professor of Medicine at Harvard Medical School and also the Founding Director of the Resynchronization and Advanced Cardiac Therapeutics Program, at the Massachusetts General Hospital Heart Center.

Dr. Singh received his medical degree from BJ Medical College, Pune University, India. He completed his internal medicine residency, cardiology and cardiac electrophysiology fellowships at Mass General. He also earned a doctorate from Oxford University, a master of science in clinical investigation from MIT-Harvard and a research fellowship at the Framingham Heart Study.

• Risk stratification for sudden cardiac death and worsening heart failure. Dr. Singh has done extensive work with the Framingham Heart Study and the MADIT Study group and published several landmark manuscripts.
• Patient selection and predicting response to cardiac resynchronization therapy. Dr. Singh has developed and built a new multidisciplinary program at Massachusetts General Hospital to care for patients with heart failure and implanted devices. His research work has led to the development of a novel response score to predict clinical outcome in this patient group.

• Coronary venous anatomy and novel ventricular lead implantation strategies. Dr. Singh has used novel rotational venography and imaging techniques to propose and substantiate new coronary venous anatomy classification and redefine the best views for lead implantation. Dr. Singh published on the importance of left ventricular lead position and developed new implantation protocols, some of which are being tested prospectively in clinical studies.

• Image integration strategies and multimodality imaging for cardiac resynchronization therapy. Dr. Singh has done some novel work integrating computed tomography, ultrasound and fluoroscopy to create better clinical strategies to facilitate device implantation.

• Device diagnostics and remote monitoring in heart failure patients. Dr. Singh's recent work has focused on the use of remote monitoring and device diagnostics to prognosticate and manage patients.

• Newer drugs and catheter ablation strategies of atrial fibrillation. Dr. Singh is actively engaged in research examining newer drug therapies for atrial fibrillation. His research interests also examine novel approaches to enhance patient selection, imaging and ablative techniques for treating atrial fibrillation.
