心包摩擦音和心电图ST段抬高是识别心包炎的两个临床征象。但是在急性心梗病人即使出现了心包摩擦音,也很少见到ST段抬高,相反,许多急性下壁心梗的病人会出现胸导ST段压低,为了探讨其临床意义,本研究对157例首次急性Q波型下壁心梗发作病人的资料进行了分析。方法与结果病人均经肢导ST段抬高、有Q波和血清肌酸激酶及MB同功酶增高确诊。心梗后24h内胸导上J点后80ms处ST段压低至少1mm诊断为ST段压低。压低持续72h为持续性。入院3天内听到心包摩擦音者考虑合并心包炎。第3天检
Pericardial Friction and Electrocardiogram ST segment elevation are two clinical signs of pericarditis. However, even in patients with acute myocardial infarction, pericardial frictional sound rarely seen in ST-segment elevation, on the contrary, many patients with acute inferior myocardial infarction thoracic ST segment depression occurs, in order to explore the clinical significance of this study of 157 The first case of acute Q wave inferior myocardial infarction patients were analyzed. Methods and Results Patients were confirmed by ST-segment elevation, Q wave and elevated serum creatine kinase and MB isoenzyme. ST-segment depression was observed at 80 ms at J-point at 24-min after myocardial infarction and at least 1 mm was diagnosed as ST-segment depression. Low for 72h sustained. Within 3 days of admission to hear pericardial friction tone consider pericarditis. Day 3 seized
