Cardiac Pressure-Volume Loops

The video tutorial explains cardiac pressure-volume loops using the left ventricle as an example. It covers the phases of the cardiac cycle, including ventricular filling, isovolumetric contraction, ventricular ejection, and isovolumetric relaxation. The tutorial also discusses the significance of the axes, direction of the loop, and key volumes such as end systolic, end diastolic, and stroke volume.
