Mechanisms of Contractility in PV Loops: Understanding Myocardial Fiber Tension
Pressure-volume (PV) loops are a cornerstone in understanding cardiac physiology, offering a graphical representation of the relationship between pressure and volume within the heart during a cardiac cycle. These loops provide critical insights into ventricular function, particularly contractility, which is the intrinsic ability of the heart muscle (myocardium) to generate force during contraction, independent of … Read more
