The aim of the study was to evaluate standard 12-lead electrocardiogram (ECG) criteria and to compare them with dynamic vector cardiography in patients with chronic right bundle-branch block for diagnosing acute myocardial infarction. We used standard 12-lead ECGs recorded on admission and after 12-24 h and compared them with dynamic vector cardiography with trend analysis during the first 12 h. In patients with right bundle-branch block, ST segment changes occurred in the same way as for patients with narrow QRS complexes. By adding 4 h of continuous vector cardiographic monitoring we were able to identify patients with acute myocardial infarction with a high diagnostic accuracy.
本研究的目的是评估标准12导联心电图（ECG）标准，并将其与慢性右束支传导阻滞患者的动态向量心电图进行比较，以诊断急性心肌梗死。我们使用了入院时和12 - 24小时后记录的标准12导联心电图，并将其与最初12小时内进行趋势分析的动态向量心电图进行比较。在右束支传导阻滞患者中，ST段改变的发生方式与QRS波群狭窄的患者相同。通过增加4小时的连续向量心电图监测，我们能够以较高的诊断准确性识别急性心肌梗死患者。
