title: Physiological significance of pressure-volume relationship: a load-independent index and a determinant of pump function.
abstract: Pressure-volume relationship permits conceptual integration with time-varying elastance, stress-strain relationship, and pressure-volume area. It has also superior usefulness to other indexes, both as a load-independent index of ventricular contractility and as a determinant of ventricular pump function.
