许多急性下壁心肌梗死(简称下壁心梗)患者,有胸前导联ST段下移,其短暂和持续ST段下移的发生率及临床意义尚有争议.鉴于前壁和后壁心肌电活动是相对应的,下壁心梗过程中胸前导联 ST(?)段下移就可以表示后壁受累。解剖学上穿壁性心梗可发生心梗相关的心包炎.作者假设急性下壁心梗患者胸前导联 ST段下移与心梗相关的心包炎有关.方法:157例首次急性 Q 波型下壁心梗患者,心梗24h 内 V_1、V_2、V_3中任一或多导联 ST 段(J 点后80ms)下移≥1mm,持续≥72h,被认为持续性 ST 段下移.入院后72h 内发现心包摩擦音就诊断为心梗相关的心包炎.入院三天内在两维超声心动图的长轴和短轴图象上分析左心室室壁11个节段活动情况,计算左心室室
In many patients with acute inferior myocardial infarction (referred to as inferior myocardial infarction), there is controversy regarding the incidence and clinical significance of shortening and continuous ST-segment elevation of the anterior thoracic lead in ST segment. Electrical activity is corresponding to the process of inferior myocardial infarction ST (?) Down the chest lead can be involved in the posterior wall involvement. Anatomy of myocardial infarction may occur myocardial infarction-related pericarditis .It is hypothesized that patients with acute inferior myocardial infarction in chest lead ST-segment down and myocardial infarction-related pericarditis.Methods: 157 cases of the first acute Q wave Type MI patients with myocardial infarction within 24 hours V_1, V_2, V_3 in any one or more lead ST segment (J point 80ms) down ≥ 1mm, sustained ≥ 72h, was considered ST segment down. Within 72 hours after the discovery of pericardial friction sound cardiomyopathy diagnosis of myocardial infarction related pericarditis.Admission within three days of two-dimensional echocardiography in the long axis and short axis image analysis of left ventricular wall 11 segments of activity, calculate the left ventricular
