Abstract

The results of vectorcardiograms were compared with those of the left ventriculograms and scintigrams with thallium-201 in cases of myocardial infarction to confirm the vectorcardiographic criteria of the present authors. The percentage of agreement between the VCG and scintigram was 82.5% and higher than the percentage of agreement between the VCG and the left ventriculogram. The percentage of disagreement between the negative finding in the VCG and the positive finding in the scintigram was 5.1% and consequently, a close relation was found between the VCG and scintigram. However, as the possibility of infarction was high in cases in which the scintigram finding was positive, the vectorcardiographic criteria in cases in which the VCG findings were negative were rechecked and partially corrected. Consequently the percentage of negative findings were decreased to 3.2%. Our next step was to perform the following prospective study which confirmed that the disagreement found in the corrected criteria (1.0%) was in fact less than what had been observed in the initial criteria (5.0%). Accordingly, it can be concluded that the corrected vectorcardiographic criteria in myocardial infarction may be the more reliable and useful in determining the location of the infarcted area.

摘要

在心肌梗死病例中，将心电图向量图的结果与左心室造影和铊-201闪烁图的结果进行比较，以确认作者提出的心电图向量图标准。心电图向量图与闪烁图之间的一致性百分比为82.5%，高于心电图向量图与左心室造影之间的一致性百分比。心电图向量图阴性结果与闪烁图阳性结果之间的不一致百分比为5.1%，因此，发现心电图向量图与闪烁图之间存在密切关系。然而，由于闪烁图结果为阳性的病例中梗死可能性较高，对心电图向量图结果为阴性的病例中的心电图向量图标准进行了重新检查并部分修正。因此，阴性结果的百分比降至3.2%。我们的下一步是进行以下前瞻性研究，该研究证实，修正标准中发现的不一致（1.0%）实际上低于初始标准中观察到的不一致（5.0%）。因此，可以得出结论，心肌梗死中修正后的心电图向量图标准在确定梗死区域位置方面可能更可靠、更有用。
