Cardiac Mechanics - Preload, Afterload, Contractility, Ejection Fraction, and Cardiac Output

Explore the fundamental principles of cardiac mechanics in this comprehensive 30-minute video lecture. Delve into the factors influencing preload, afterload, and contractility, and learn how to calculate and measure ejection fraction and cardiac output/index. Understand the Frank-Starling curve and its significance in cardiovascular physiology. Begin with an introduction and clear learning objectives, then progress through detailed explanations of each key concept. Conclude with a summary that reinforces the main points, enhancing your understanding of cardiovascular physiology and its clinical applications.
