There is some evidence of the association between ST-segment elevation in the V4R chest lead and the likelihood of anterior wall myocardial infarction; however, the link of this phenomenon with the location and the severity of the coronary involvements in such patients remains uncertain. We aimed to investigate the ST-segment elevation in V4R leads in patients with anterior myocardial infarction and also its effect on prognosis as well as the detection and prediction of the location of arterial stenosis in coronary angiography.

前壁心肌梗死患者V4R导联ST段抬高的意义

有证据表明 V4R 胸导联 ST 段抬高与前壁心肌梗死的可能性之间存在关联；然而，这种现象与此类患者冠状动脉受累的位置和严重程度之间的联系仍不确定。我们旨在研究前壁心肌梗死患者 V4R 导联 ST 段抬高及其对预后的影响以及冠状动脉造影中动脉狭窄位置的检测和预测。
