GAURAV A. UPADHYAY, MD, FACC, FHRS is an expert in cardiac rhythm devices and Associate Professor at the University of Chicago Medicine. He is Vice Chief of Cardiology, Promotions & Appointments. He is the Director of the Pacing & Defibrillation Device Clinic and also Director of the Heart Station, overseeing ambulatory monitoring and ECGs Dr. Upadhyay’s clinical research interests include elucidating mechanisms and approaches for conduction system pacing (CSP), device optimization strategies for cardiac resynchronization therapy (CRT) in heart failure, autonomic modulation for syncope and arrhythmia, and large database analysis for catheter ablation of arrhythmias including atrial fibrillation.
Paralleling his focus on patient care, Dr. Upadhyay is an active clinical investigator. An invited national and international speaker, he has authored or delivered over 300 manuscripts, editorials, book chapters, and abstracts. He is also deeply committed to teaching, and seeks out opportunities to collaborate and engage trainees in teaching at the bedside as well as in transforming models of care.
