Lesson 1
How Is A Heartbeat Regulated
Start course

Professor Saltzman talks about electrical conductivity in the heart. He describes the role of ion channels and pumps in transporting sodium, potassium, and calcium ions to create action potential. This propagation of signal from the sinoatrial node through different tissues, which can be replaced by a pacemaker, eventually stimulates contraction of muscle fibers throughout the heart. How each wave trace corresponds to the events caused by depolarization/repolarization of different heart tissues. Professor Saltzman, W. Mark.
