From: Diastolic dysfunction and diastolic heart failure: diagnostic, prognostic and therapeutic aspects
In the left screen, methodological outline for the measurement of Doppler transmitral indexes of diastolic function. In the right screen, normal diastolic pattern (upper part) and pattern of abnormal relaxation (lower part). A = atrial velocity (m/s), DT = deceleration time of E velocity (ms), E = early diastolic velocity (cm/s), IVRT = isovolumic relaxation time (ms)
