Cardiovascular Physiology - Electrical Conductivity in the Heart - Lecture 15

Explore cardiovascular physiology in this 46-minute lecture from Yale University's Frontiers of Biomedical Engineering course. Delve into the intricacies of electrical conductivity in the heart, focusing on the generation and propagation of electrical potential in cardiac cells. Learn about the crucial role of ion channels and pumps in transporting sodium, potassium, and calcium ions to create action potential. Discover how electrical signals propagate from the sinoatrial node through various heart tissues, stimulating muscle fiber contractions. Examine the electrocardiograph (EKG) and understand how wave traces correspond to depolarization and repolarization events in different heart tissues. Gain insights into the lipid membrane, electric potential, and the cardiac conduction system. Compare electrophysiological differences between the nervous system and the heart. Recorded in Spring 2008, this lecture offers a comprehensive exploration of cardiovascular physiology, suitable for biomedical engineering students and those interested in cardiac function.
