右室缺血的心电图特征是右侧胸前导联,特别是V_4R导联的ST段抬高。晚近,作者们观察到一组急性下壁心肌梗塞合并右室缺血患者,其胸前导联ST段降低与下壁ST段抬高的比值较未合并右室缺血者为轻。因此,作者们对STv_2压低与STaVF抬高的比值,在早期急性下壁心肌梗塞合并右室缺血的诊断价值进行了研究。方法:68例急性下壁心肌梗塞患者(男58例、女10例),平均年龄57士12岁(27-80岁)。急性心肌梗塞按以下诊断标准:(1)胸痛持续在3小时以上;(2)二个以上的下壁导联有肯定的ST段抬高;(3)含服硝酸甘油对缓解胸痛及ST段
The ECG characteristic of right ventricular ischemia is the right anterior chest lead, especially the ST elevation in the V_4R lead. Recently, the authors observed a group of patients with acute inferior myocardial infarction complicated by right ventricular ischemia, the ratio of ST-segment elevation in the anterior chest lead to ST-segment elevation in the inferior wall was less than those without right ventricular ischemia. Therefore, the authors compared the ratio of STv_2 depression to STaVF elevation in the diagnosis of early acute inferior myocardial infarction with right ventricular ischemia. Methods: 68 patients with acute inferior myocardial infarction (58 males and 10 females) with an average age of 57 ± 12 years (27-80 years). Acute myocardial infarction according to the following diagnostic criteria: (1) chest pain continued for more than 3 hours; (2) more than two inferior leads have positive ST elevation; (3) containing nitroglycerin to relieve chest pain and ST segment
