Numerous measures of left ventricular diastolic function are currently in clinical use. To determine which echo-Doppler left ventricular diastolic function measurements are most feasible in the clinical echocarcliographic laboratory, the success rate, recording time taken by the sonographer, and inter-reader variability were calculated for transmitral valve inflow, pulmonary vein flow, tissue Doppler imaging, and color M-mode flow propagation velocity in 80 inpatients.
