在急性心梗的患者中,梗塞区很少出现反映心包炎的PQ段压低。通过听诊、心电图和二维超声心动图连续检查171例有急性Q波型下壁心肌梗塞的患者。患者入院后头3天由两位以上检查者查到心包摩擦音后确定心包炎诊断。PQ段压低标准是在肢体导联和胸导联上PQ段比TP段降至少0.5mm,并持续超过24h。A组14例有PQ段压低而B组
In patients with acute myocardial infarction, there is very little evidence of pericarditis in the infarct zone PQ depression. A total of 171 consecutive patients with acute Q wave inferior wall myocardial infarction were examined by auscultation, electrocardiogram and two-dimensional echocardiography. Patients admitted to the hospital after the first three days by more than two examiner found pericardial friction sound after the diagnosis of pericarditis. The PQ segment depression criteria is that the PQ segment is at least 0.5 mm lower than the TP segment in the limb lead and chest lead and lasts longer than 24 h. A group of 14 patients with PQ depression and B group
