Unlocking the mechanics of the human heartbeat is essential for acing cardiac physiology. In this lecture, we break down the Cardiac Cycle & Dynamics into 7 distinct phases, simplifying complex concepts like the Wiggers Diagram and Pressure-Volume (PV) Loops for medical exams like USMLE Step 1, NEET-PG, INI-CET, PLAB, and FMGE.

We start with the "Rules of the Game"—understanding pressure gradients and valve mechanics—before walking through the full cycle from atrial contraction to ventricular filling. You will also learn how to calculate vital stats like Stroke Volume, Cardiac Output, and Ejection Fraction, and understand how the heart "tunes its engine" using Preload, Afterload, and Contractility. Finally, we decode clinical correlations, including the physiological splitting of the S2 heart sound and what pathological splitting tells us about heart health.
