Methodology for measuring pulsed Tissue Doppler derived time to peak Sm and time to onset Sm (left panel). In the right panel measurements of time to peak Sm (upper panel) and of time to onset Sm (lower panel) are depicted. Am = Myocardial atrial velocity, CTm = Contraction time, Em = Myocardial early diastolic velocity, RTm = Myocardial relaxation time, Sm = Myocardial systolic velocity.
