Episode 173: The Road to a Healthy Heart – Part 1

This week, Jonathan is joined by Greg Marcus, Endowed Professor of Atrial Fibrillation and Professor of Residence (Medicine) at the University of California, San Francisco, USA, to explore advances in the field of electrophysiology, and how substances such as coffee, alcohol, and cannabis have an effect on cardiac arrythmias, physical activity, and sleep. They further dive into the aims and results of the Health eHeart study, and how technology such as smartwatches can be used in heart disease.
