Isovolumic relaxation time shortens significantly during the three months after birth

open access: closedJournal of the American Society of Echocardiography, 2004
Although most Doppler-derived left ventricular diastolic function parameters undergo permanent changes during growth and maturation, isovolumic relaxation time (IVRT) normalized to heart rate has a constant value from the fourth month of life through adolescence. No reference values exist for IVRT in babies less than 3 months of age.

Evaluation of Time Course of Left Ventricular Isovolumic Relaxation in Humans

open access: closed, 1987
Weiss and coworkers [1] first determined, in an open-chest, right-heart-bypass animal model, that left-ventricular-pressure decay during isovolumic relaxation can be approximated by a monoexponential function. Their technique required that the derived or best-fit monoexponential curve for the pressure data decay asymptotically toward zero pressure. [1,
