| Aw, peak atrial systolic motion velocity; Ew, peak early diastolic motion velocity; IVS, interventricular septum recorded from its base; LV, left ventricle recorded from lateral site of the mitral annulus; RV, right ventricle recorded from lateral site of the tricuspid annulus; Sw, peak systolic motion velocity. In the children group, two peak waveforms(S1w, S2w) were noted during systole in the IVS and LV wall. | |||
