摘要：

The ratio of peak early diastolic (E) and peak late diastolic (A) velocities, measured from the Doppler mitral waveform, has been used widely to assess left ventricular diastolic function.1-10 This ratio is also affected by age,2,11 heart rate12 and loading conditions.4,6,9 In some studies, Doppler waveforms have been recorded by sampling at the mitral anulus,1-4 in others the sample volume has been placed between the free margins of the mitral leaflets,5-7 and in some the measurement site has not been clearly defined.8-10 There is no consensus regarding the optimal position. In the present study we measured E A ratio at both the mitral tips and anulus in 300 consecutive patients to determine if sample volume location had an important influence. © 1991.
