Introduction to Tau (Diastolic Relaxation Time): Understanding the Science of Cardiac Relaxation
What Is Tau (Diastolic Relaxation Time)? Defining Tau in Cardiac Physiology In cardiovascular physiology, Tau represents the time constant of left ventricular relaxation — a key parameter used to describe how efficiently the heart muscle relaxes during diastole. It quantifies the exponential decline in ventricular pressure after systole when the myocardium transitions from contraction to … Read more
