Measurement of Cardiac Time Intervals by Doppler Tissue M-Mode Imaging of the Anterior Mitral Leaflet

Measurement of isovolumic periods and LV ejection time was feasible and reliable by DTI M-mode analysis of the anterior mitral valve leaflet. The DTI method can, therefore, be used for obtaining information of global events in the cardiac cycle from the same heart beat as used for analysis of regional cardiac performance.
