85 vectorcardiograms, characterized by anteriorly oriented horizontal ventricular loop, were analized in order to evaluate if this pattern can be considered diagnostic at all for strictly posterior myocardial infarction. Records were divided into two groups according to positivity or negativity of clinical history for myocardial infarction. Records consistent with right ventricular hypertrophy were ruled out. Nine parameters related to ventricular depolarization and repolarization were measured and the values were submitted to statistical analysis. The study showed that:--selection of the two groups was correct, because of first group's homogeneity and control group's unhomogeneity;--mean values of the nine parameters did not differ significantly in the two groups;--single parameter into each group was unrelated to others. As a consequence, criteria at the time in use for diagnosis of strictly posterior myocardial infarction seem not to be useful, as other conditions beside myocardial infarction or right ventricular hypertrophy are able to determine the same vectorcardiographic pattern.
为了评估以向前的水平心室环为特征的85份心电向量图能否被视为诊断单纯后壁心肌梗死的依据，对这些心电向量图进行了分析。根据心肌梗死临床病史的阳性或阴性将记录分为两组。排除与右心室肥厚一致的记录。测量了与心室去极化和复极化相关的九个参数，并对这些值进行了统计分析。研究表明：——两组的选择是正确的，因为第一组具有同质性，而对照组具有异质性；——两组中九个参数的平均值没有显著差异；——每组中的单个参数与其他参数无关。因此，目前用于诊断单纯后壁心肌梗死的标准似乎没有用处，因为除心肌梗死或右心室肥厚外的其他情况也能够产生相同的心电向量图模式。
