End-Systolic Pressure-Volume Relationship (ESPVR): The Ultimate Guide to Cardiac Function

Introduction to ESPVR The end-systolic pressure-volume relationship (ESPVR) is one of the most important concepts in cardiovascular physiology. It provides a load-independent measure of cardiac contractility, making it an invaluable tool in both research and clinical practice. By analyzing the slope of the ESPVR line on a pressure-volume (PV) loop, clinicians and researchers can gain … Read more

Pmax derivation of contractility (ESPVR): Fundamentals and Basic Concepts

Introduction The Pmax derivation of contractility is a crucial concept in cardiovascular physiology, particularly in understanding the heart’s ability to generate force during systole. This principle is closely related to the End-Systolic Pressure-Volume Relationship (ESPVR), which serves as a key indicator of myocardial contractility. By analyzing Pmax, or the theoretical maximum pressure the ventricle can … Read more
