在100例右前斜位左室造影片中，测定了左室短轴与长轴的关系。这种关系采取了广泛的体积，用于推导出一个理论上正确的公式，用于确定心室容积的超声心动图。最终公式为：V = [7.0/2.4 + D]（D3），其中V =体积，D =超声心动图测量的内部尺寸。在12例无心功能不全的患者中，无论左心室大小，该方程均能准确、直接地计算出收缩末期和舒张末期容积。然而，在12例表现出左心室不同步的血管造影和超声心动图确定的体积之间的相关性是穷人。因此，在冠状动脉疾病和可能的左心室不同步的患者中，建议谨慎使用时间运动超声心动图来计算心室容积。
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 enddiastolic 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.
