摘要
探讨急性心肌梗塞部位对应导联ST段压低的意义。对245例初发急性心肌梗塞（AMI）患者发病72小时内12导联心电图ST段变化进行了分析。结果：合并梗塞部位对应导联ST段压低者占38．78％；单变量分析合并ST段压低者多见于高龄及女性，其高血压、糖尿病、广泛前壁心肌梗塞（心梗）、下壁合并后壁或右室心梗、心原性休克、心力衰竭、恶性心律失常等并发率均与无ST段压低者有显著性差异（P均＜0．001）；多变量分析示：高龄、糖尿病、广泛前壁梗塞、下壁合并后壁梗塞或右室梗塞可作为梗塞部位对应导联ST段压低的独立指征。表明AMI早期梗塞部位对应导联ST段压低是一个简单、快速、有效的初步判断梗塞范围和预后的良好指标。
The significance of opposite - infarction leads STsegment depression in patients with acute myocardialinfarction was studied. The ST - segment changes of 12- lead electrocardiogram in 245 patients with acute myocardialinfarction (AMI) during early 72 hours wereanlyzed. The results were as follows: (1 ) 95 patientshad opposite - infarction leads ST - segment depression(38. 78% ). (2) single variate analysis showed the patientswith opposite - infarction leads ST - segment depressionwere much more commonly the aged, thefamales, and those with hypertension, diabetes, extensiveanterior myocardial infarction and inferior myocardialinfarction with lateral right ventricular infarctionas compared with those without opposite - infarctionleads ST- segment depression. (3) patients withopposite - infarction ST - segment depression had ahigher incidence of cardiac shock,heart failure and malignantarrhythmias than those without ST - segmentdepression (P < 0. 001 ). (4 ) the mortality of patientswith opposite - infarction ST - segment depression washigher than those without ST - segment depression(P<0.05). Multiple variate analysis showed the elder,diabetes,extensive anterior myocardial infarction,inferiormyocardial infarction associated with posterior or rightventricular infarction were independent signs of opposite- infarction leads ST - segment depression whichreflected a poor diagnosis of AMI. This study suggeststhat the opposite - infarction lead ST - segment depressionis a simple and effective sign for the assessment ofthe extent and the prognosis of AMI.
