Pressure-Volume Loops and the Cardiac Cycle - Cardiophysiology

Medicosis Perfectionalis via YouTube

Overview

Explore the intricacies of pressure-volume loops and the cardiac cycle in this comprehensive cardiophysiology video. Delve into the differences between systole and diastole, examining the phases of isovolumetric contraction, rapid ejection, reduced ejection, isovolumetric relaxation, rapid filling, and reduced filling. Learn how cardiac output is calculated and understand the relationship between mean systemic arterial blood pressure, cardiac output, and total peripheral resistance. Discover key concepts such as ejection fraction, end-systolic volume, and end-diastolic volume, and their significance in heart failure. Analyze the slope of pressure-volume cardiac loops to understand contractility and inotropic properties. Explore various cardiac terms including inotropic, chronotropic, dromotropic, and bathmotropic effects. Gain insights into venous return, central venous pressure, and pulmonary capillary wedge pressure to enhance your understanding of cardiovascular physiology.
