In order to investigate the relation between the infarcted area in myocardial infarction and the change of the QRS loop, the following method was tried. The normal QRS loops in 3 planes were constructed with the digital computer. Then the vector of an optional segment corresponding to infarction was diminished and the QRS loops were constructed. The comparison of the QRS loops in clinical cases and in the construction method was made and the vectorcardiographic findings to estimate the infarcted area were discussed.
为了研究心肌梗死的梗死面积与QRS环变化之间的关系，尝试了以下方法。用数字计算机构建了三个平面的正常QRS环。然后减小对应于梗死的任意节段的向量，并构建QRS环。对临床病例中的QRS环与构建方法中的QRS环进行了比较，并讨论了用于估计梗死面积的向量心电图表现。
