下壁心肌梗塞伴右室心肌梗塞时,可根据心电图右侧胸导联特征性改变作出诊断;但右侧胸导联并不常规记录。病理研究证明,大范围右室心肌梗塞通常发生于下壁心肌梗塞时,因为两者都由右冠脉近侧阻塞所致、因而,主要反映下壁电活动的Ⅱ、Ⅲ、αVF导联,在右室心肌梗塞时可能有明
Lower wall myocardial infarction with right ventricular myocardial infarction, ECG can be based on the right to change the characteristics of the chest lead to make a diagnosis; but the right chest lead is not routinely recorded. Pathological studies have shown that a wide range of right ventricular myocardial infarction usually occurs in the inferior myocardial infarction, because both are caused by the proximal obstruction of the right coronary artery, therefore, mainly reflects the lower wall electrical activity of Ⅱ, Ⅲ, αVF lead, In the right ventricular myocardial infarction may be bright
