Accession:CMO:0001747 term browser browse the term
Definition:A calculated hemodynamic value related to the ability of the heart left ventricle to relax. Tau is calculated as an exponential function of the change in intraventricular pressure during the diastolic isovolumic left ventricular pressure decrease.
Synonyms:exact_synonym: Left ventricular relaxation time constant;   P/(−dP/dt);   T;   Tau;   time constant of left ventricular relaxation
 broad_synonym: left ventricular function
