The relation of minor and major axes of the left ventricle was determined in 100 left ventriculograms performed in the right anterior oblique projection. This relation taken over a wide range of volumes was used to derive a theoretically correct equation for determination of ventricular volume by echocardiography. The final equation was: V =[7.0/2.4 +d] (D3), where V = volume and D = the echocardiographically measured internal dimension. In 12 patients without asynergy, this equation accurately and directly calculated end-systolic and end-diastolic volumes whether the left ventricle was small or large. However, in 12 patients exhibiting left ventricular asynergy the correlation between angiographically and echocardiographically determined volumes was poor. Thus, caution is recommended in the use of time-motion echocardiography to calculate ventricular volumes in patients with coronary artery disease and possible left ventricular asynergy.
在100例右前斜位的左心室造影片中测定了左心室短轴与长轴的关系。在很宽的容量范围内获取的这种关系被用于推导一个理论上正确的方程式，以便通过超声心动图测定心室容量。最终的方程式为：V =[7.0/2.4 +d] (D3)，其中V =容量，D =超声心动图测量的内径。在12例无运动失调的患者中，无论左心室是大还是小，该方程式都能准确、直接地计算出收缩末期和舒张末期容量。然而，在12例表现出左心室运动失调的患者中，血管造影测定的容量与超声心动图测定的容量之间的相关性较差。因此，对于患有冠状动脉疾病且可能存在左心室运动失调的患者，在使用时间-运动超声心动图计算心室容量时建议谨慎。
