正常心脏中模拟心肌梗死的向量心电图异常。

Can Med Assoc J. 1964 Apr 11;90(15):903-9.

During a study of the vectorcardiogram in the normal young heart, four individuals were found in whom the QRS loops, surprisingly, fulfilled the usual criteria for the diagnosis of myocardial infarction. These vectorcardiograms are described in detail. Two of the four electrocardiograms are within normal limits. These abnormal vectorcardiographic patterns are probably due to a congenital variant in left ventricular conduction. This rare condition is of clinical significance because it may result in diagnostic confusion in older patients.

在一项针对正常年轻心脏向量心电图的研究中，发现有四人的QRS环令人惊讶地符合心肌梗死诊断的通常标准。详细描述了这些向量心电图。四份心电图中有两份在正常范围内。这些异常的向量心电图模式可能是由于左心室传导的先天性变异。这种罕见情况具有临床意义，因为它可能在老年患者中导致诊断混淆。
