目的:探讨急性下壁心肌梗死合并胸前导联 ST 段压低的临床意义,方法:选取急性下壁心肌梗死患者134例,将心电图 V1-6中2个或2个以上导联 ST 段压低0.1mv 以上的72例分为Ⅰ组,无 ST 段下移或下移在0.1mv 以内的62例分为Ⅱ组,观察两组间心肌硬 CK 峰值平均值的差异及住院期间出现各种合并症如心功能不全,心律失常,心源性休克及病死率的差别。结果:Ⅰ组 CK 峰平均值出现合并症比例病死率均高于Ⅱ组,两组间差异明显(P<0.01)。结论:急性下壁心肌梗死合并胸前导联 ST 段抬高提示梗死面积广泛,住院期间合并症发生率及病死率高,预后差,是一种简便、无创的一临床检测手段,可对心肌梗死患者的治疗及判断预后提供积极的帮助。
Objective: To investigate the clinical significance of ST segment depression in patients with acute inferior myocardial infarction complicated with thoracic aorta.Methods: A total of 134 patients with acute inferior myocardial infarction were selected and ST-segment depression was induced in 2 or more leads of electrocardiogram V1-6 by 0.1 mv above 72 cases were divided into group Ⅰ, without ST-segment down or down within 0.1mv in 62 cases were divided into two groups were observed between the two groups, the average difference between the peak value of myocardial ck and various complications during hospitalization Such as cardiac insufficiency, arrhythmia, cardiogenic shock and mortality differences. Results: The average mortality of CK in Ⅰ group was higher than that in Ⅱ group, the difference was significant (P <0.01). Conclusion: Acute inferior myocardial infarction combined with ST-segment elevation of the thoracic aorta suggest a wide range of infarct size. The incidence of comorbidities and mortality during hospitalization is high, and the prognosis is poor. It is a simple and noninvasive means of clinical examination, Infarction treatment and prognosis provide a positive help.
