[目的]探讨心电图对应导联出现ST段压低在急性心肌梗死患者诊断中的临床意义。[方法]回顾性分析2008年1月～2010年3月,我院收治的急性心肌梗死患者中,66例心电图对应导联出现ST段压低患者,设为观察组;选取同期诊断为急性心肌梗死患者但心电图对应导联未出现ST段压低的50例患者,设为对照组。统计两组患者出现其他冠脉病变、临床心功能分级、左心射血分数、严重心律失常、死亡发生率,总结心电图对应导联出现ST段压低在急性心肌梗死患者诊断、治疗中的临床意义。[结果]经研究显示,两组患者中,观察组患者的冠脉病变率、严重心律失常发生率、死亡率均明显高于对照组患者,P值均﹤0.05,差异有统计学意义;心功能分级、左心射血分数均较对照组差,P值均﹤0.05,差异有统计学意义。[结论]心电图对应导联出现ST段压低是急性心肌梗死患者合并其他冠脉病变的重要信号,临床应及早采取干预治疗措施,以降低死亡率。
[Objective] To investigate the clinical significance of ST-segment depression induced by ECG leads in the diagnosis of patients with acute myocardial infarction. [Methods] From January 2008 to March 2010, retrospective analysis of 66 patients with acute myocardial infarction admitted to our hospital, ST-segment depression was observed in the corresponding lead of 66 electrocardiogram patients, and the observation group was set as the observation group. The diagnosis of acute myocardial infarction Fifty patients with ST-segment depression who did not appear on the corresponding electrocardiogram leads were selected as the control group. Statistics of other two groups of patients with coronary lesions, clinical cardiac function classification, left ventricular ejection fraction, severe arrhythmia, the incidence of death, summarizes the ECG lead ST segment depression in the diagnosis and treatment of patients with acute myocardial infarction clinical significance . [Results] The study showed that the two groups of patients, the observation group of patients with coronary artery disease rate of coronary heart disease, severe arrhythmia and mortality were significantly higher than those in the control group, P <0.05, the difference was statistically significant; heart Functional classification, left ventricular ejection fraction were worse than the control group, P values were <0.05, the difference was statistically significant. [Conclusion] ST-segment depression induced by ECG leads is an important signal in patients with acute myocardial infarction complicated by other coronary lesions. Intervention treatment should be taken as early as possible to reduce mortality.
