Cardiovascular | Cardiac Cycle

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this cardiovascular physiology lecture, Professor Zach Murphy discusses the cardiac cycle, walking you through each mechanical and electrical event that occurs during a single heartbeat. This session integrates pressure, volume, valve function, and heart sounds to help you master this foundational concept. We begin by outlining the phases of the cardiac cycle, including atrial systole, isovolumetric contraction, ventricular ejection, isovolumetric relaxation, and ventricular filling. You’ll learn how these phases are coordinated with ECG events, heart sounds (S1 and S2), and changes in aortic, ventricular, and atrial pressures. The lecture also explores how valve dynamics regulate blood flow—detailing the opening and closing of the mitral, tricuspid, aortic, and pulmonary valves and how these actions generate the normal heart sounds and potential murmurs.
