Yaariv Khaykin

Yaariv Khaykin is a Canadian cardiologist and cardiac electrophysiologist specializing in arrhythmia management, digital health, and cardiac data systems. He serves as Chief Medical Information Officer at Southlake Regional Health Centre and Chief Medical Officer at Myant Health, and is an Associate Professor of Medicine at the University of Toronto. His work focuses on cardiac electrophysiology, clinical informatics, and the integration of digital technologies into cardiovascular care.

Education Khaykin pursued his undergraduate studies in molecular genetics and biology at the University of Toronto before entering medical school. He earned his Doctor of Medicine (MD) from the University of Toronto in 1996.

He completed postgraduate training in general internal medicine and cardiology at the University of Toronto, including serving as Chief Cardiology Resident at Sunnybrook Health Sciences Centre. He subsequently undertook a fellowship in cardiac electrophysiology at the Cleveland Clinic Foundation in the United States.

He has also completed additional professional training, including a Physician Leadership Certificate from the Ontario Medical Association.

Career Khaykin has held multiple clinical, academic, and leadership roles in cardiology and health systems innovation. Since 2004, he has served as a staff cardiologist and electrophysiologist at Southlake Regional Health Centre in Newmarket, Ontario, where he later became Chief Medical Information Officer from 2014 to present.

Since 2012, he is the founder and CEO of PACE Cardiology and director of the Newmarket Electrophysiology Research Group since 2005. In 2024, he was appointed Chief Medical Officer of Myant Health, focusing on digital health technologies and remote monitoring solutions.

In academia, Khaykin has been affiliated with the University of Toronto since 2010, serving as Assistant Professor before being promoted to Associate Professor in 2025.

Earlier in his career, he contributed to regional cardiology initiatives, including leading the York–Simcoe–Muskoka Arrhythmia Management and Guidelines Project, which developed standardized referral and care pathways. He has also been involved in physician education and industry-supported electrophysiology training programs.

Research Khaykin's research focuses on cardiac electrophysiology, arrhythmia management, and the application of digital technologies in cardiovascular care. His work has included the development of cardiac data management systems, clinical decision-support tools, and regional care models for arrhythmia treatment.

He has led initiatives integrating clinical informatics into cardiology practice, particularly in the use of electronic medical records, standardized order sets, and remote monitoring systems to improve patient outcomes. His research also addresses evidence-based approaches to atrial fibrillation management , catheter ablation strategies, and healthcare system optimization through data-driven methodologies.
