The developing of cuantitative angiographic procedures for evaluating the left ventricular efficiency have displaced most of the simple hemodynamic methods. The calculation of the left ventricular volume by usual ventriculography yields, as a rule, magnified values. The purpose of this paper is to determine the equation of the regression line means of which the real left ventricular volume can be calculated. A series of 12 normal hearts obtained from accidentaly deceased adult individuals (this necropsy material was afforded by the Forensic Medicine Department of México City). Previously measured amounts of a contrast substance were injected into the left ventricular cavity. The heart was filmed in a position equivalent to the chest RAO. The volume of the left ventricle was calculated using monoplane Sandler and Dodge cineventriculographic method. The results were submitted to statistic analysis. Confrontation of calculated and real values rendered a significative "r" (0.7374) and a non-significant "p" (0.001) the regression equation obteined was: y=36.97 + (0.39 x) in which: y=real left ventricular volume. x=calculated left ventricular volume.
用于评估左心室效率的定量血管造影程序的发展已取代了大多数简单的血流动力学方法。通常通过心室造影计算左心室容积，通常会得出放大的值。本文的目的是确定回归线方程，通过该方程可以计算出实际的左心室容积。从意外死亡的成年个体中获取了一系列12个正常心脏（该尸检材料由墨西哥城法医学部提供）。将先前测量的造影剂注入左心室腔。在相当于胸部右前斜位的位置拍摄心脏。使用单平面桑德勒和道奇电影心室造影法计算左心室容积。将结果进行统计分析。计算值与实际值的对比得出显著的“r”（0.7374）和不显著的“p”（0.001），得到的回归方程为：y = 36.97 +（0.39x），其中：y =实际左心室容积，x =计算出的左心室容积。
