尸解研究表明直接测量心壁的厚度和长度,采用截头椭圆体公式,能预示人类正常或肥厚的左室心肌重量(LVM)。本文采用上述计算方法,观察临床两维超声心动图(2-DE)心肌重量测定方法的准确性和重复性,以及判定观察者的工作经验、检查质量和心壁运动异常对该方法的影响。方法 40例患者在死亡前10个月之内傲过2DE,其中37例的2DE 图适合于 LVM测定。根据 Bove 等的方法解剖心脏,游离
Autopsy studies have shown that the direct measurement of the thickness and length of the heart wall, using truncated ellipsoid formula, can predict human normal or hypertrophied left ventricular myocardial weight (LVM). In this paper, the accuracy and repeatability of clinical 2-dimensional echocardiography (2-DE) myocardial gravimetric method were observed by using the above calculation method, as well as the observational work experience, the quality of examination and the abnormality of cardiac wall motion on this method. Methods Forty patients underwent 2DE within 10 months before death, and 37 of them were fitted to LVE for 2DE. The heart is dissected according to the method of Bove et al
