Echocardiogram spectral doppler isovolumic relaxation time
General Details:
Name:
Echocardiogram spectral doppler isovolumic relaxation time
Steward:
NINDS
Definition:
Isovolumic relaxation time (IVRT) measured using spectral doppler. IVRT is an interval in the cardiac cycle, from the aortic component of the second heart sound, that is, closure of the aortic valve, to onset of filling by opening of the mitral valve. It can be used as an indicator of diastolic dysfunction.
