A correlation was made between the vectorcardiographic changes and the peak value of the L.D.H. in the serum of 21 patients with acute inferior (diafragmatic) M.I. The following vectorcardiographic variables showed changes proportional to the increase in serum L.D.H. The correlation was found to be statistically significant. The direction of the 0.025 sec vector (r = 0.63, P less than 0.005). The duration of the initial superior forces of the QRS loop (r = 0.87, P less than 0.001). The maximal leftward deviation of the initial superior QRS loop forces (r = 0.65, P less than 0.005). The maximal superior deviation of the initial QRS loop forces (r = 0.68, P less than 0.05). The ratio of the maximal superior deviation over the maximal inferior deviation of the QRS loop "QY/RY" (r = 0.76, P less than 0.001). The area under the initial superior forces of the QRS loop and over 0 degrees +/- 180 degrees axis in squared milimeters (r = 0.88, P less than 0.001). It is suggested that V.C.G. is a usefull means in assessing the extent of inferior M.I.
对21例急性下壁（膈面）心肌梗死患者的心电图变化与血清乳酸脱氢酶（L.D.H.）峰值进行了相关性分析。以下心电图变量显示出与血清L.D.H.升高成比例的变化。发现这种相关性具有统计学意义。0.025秒向量的方向（r = 0.63，P < 0.005）。QRS环初始向上力的持续时间（r = 0.87，P < 0.001）。QRS环初始向上力的最大向左偏移（r = 0.65，P < 0.005）。QRS环初始力的最大向上偏移（r = 0.68，P < 0.05）。QRS环“QY/RY”的最大向上偏移与最大向下偏移之比（r = 0.76，P < 0.001）。QRS环初始向上力在0度±180度轴上方的面积（单位：平方毫米）（r = 0.88，P < 0.001）。提示心电图在评估下壁心肌梗死范围方面是一种有用的手段。
