Normal mitral inflow velocity
Web1 de mar. de 2005 · Abstract. Tissue Doppler echocardiography (TDE) is used in the assessment of diastolic function, however, it is unclear whether the medial ( E ′ med) or lateral ( E ′ lat) annulus should be used. Our aim was to compare the diagnostic utility of E ′ med and E ′ lat. In 232 subjects left ventricular (LV) systolic and diastolic function was … WebIsovolumic relaxation time (IVRT) is a measure of time (in milliseconds) from the onset of the aortic valve closure spike artifact to the onset of the mitral valve opening spike artifact (Figs. 18-5 and 18-6 ). 17 The IVRT is obtained from the apical five-chamber view by aligning the Doppler beam midway between the LV inflow and the LV outflow ...
