From: Diastolic dysfunction and diastolic heart failure: diagnostic, prognostic and therapeutic aspects
In the left screen, methodological outline for the measurement of Tissue Doppler indexes. In the right screen, normal myocardial diastolic pattern (upper part) and pattern of abnormal myocardial relaxation (lower part). Am = myocardial atrial velocity (cm/s), CTm = myocardial contraction time (ms), DTm = myocardial deceleration time of Em(ms), Em = myocardial early-diastolic velocity (cm/s), PCTm = myocardial pre-contraction time (ms), RTm = myocardial relaxation time (ms).
