Dr. John Roshan Jacob is a Professor of Cardiology at Christian Medical College (CMC), Vellore, with approximately 25 years of clinical experience in cardiology. He completed his undergraduate and postgraduate medical studies at CMC Vellore and pursued advanced training in cardiac electrophysiology in India, the United States, and Canada. His training includes initial electrophysiology instruction under Dr. Tom Peter at the University of California, Los Angeles, followed by an adult electrophysiology fellowship at Toronto General Hospital and a paediatric electrophysiology fellowship at the Hospital for Sick Children in Toronto.

Dr. Roshan has contributed to the development of cardiac electrophysiology practice in India, including the introduction of transoesophageal electrophysiology studies in neonates. His clinical interests include ventricular tachycardia (VT) ablation and the extraction of implantable cardioverter-defibrillator (ICD) leads. He has performed VT ablation in a patient with severe ventricular dysfunction using extracorporeal membrane oxygenation (ECMO) support, described in the source profile as a first of its kind in Asia. He was also among the early physicians in India to use the Tightrail device for ICD lead extraction.

His broader cardiology practice includes the assessment and management of coronary artery disease, heart failure, arrhythmias, valvular and congenital heart disease, and other cardiovascular conditions. Dr. Roshan has published scientific papers and received professional recognition, including the AV Gandhi Prize for Excellence in Cardiology. He consults at Christian Medical College Vellore and speaks Hindi and English.
