Cardiac Cycle - Understanding Heart Function and Blood Flow

Delve into a comprehensive 1-hour 13-minute lecture on the cardiac cycle, focusing on cardiovascular physiology and cardiology. Explore the intricate events occurring in the left side of the heart, including ventricular contraction, valve closure, and the various phases of the cardiac cycle. Examine key concepts such as isovolumetric contraction, rapid and slow ventricular ejection, isovolumetric relaxation, and ventricular filling phases. Gain insights into heart sounds, pressure changes in vessels and chambers, and the graphical representation of the cardiac cycle. Analyze the timing of systole and diastole, and understand the significance of ECG readings in relation to cardiac events. This in-depth presentation provides a thorough understanding of the heart's mechanical and electrical activities, essential for medical students and healthcare professionals studying cardiovascular physiology.
