The relationship between ST segment elevation on the right precordial lead V4R and the hemodynamic, echocardiographic, and myocardial scintigrapic signs suggestive of right ventricular (RV) infarction was studied in 42 patients with acute inferior myocardial infarction. Twenty-two patients had ST segment elevation in V4R. Among these patients, a significant correlation was demonstrated between V4R ST segment elevation and the hemodynamic (p less than 0.001), scintigraphic (p less than 0.001), and echographic (p less than 0.02) criteria for acute RV infarction. These results support the validity of this new electrocardiographic sign as a practical means in aiding the clinical detection of RV involvement with acute transmural inferior myocardial infarction.
对42例急性下壁心肌梗死患者进行了研究，探讨右胸前导联V4R上ST段抬高与提示右心室（RV）梗死的血流动力学、超声心动图及心肌闪烁显像征象之间的关系。22例患者V4R导联有ST段抬高。在这些患者中，V4R导联ST段抬高与急性RV梗死的血流动力学标准（p<0.001）、闪烁显像标准（p<0.001）及超声心动图标准（p<0.02）之间存在显著相关性。这些结果支持这一新的心电图征象作为辅助临床检测急性透壁性下壁心肌梗死合并RV受累的实用手段的有效性。
