目的探析急性心肌梗死患者心律失常的发生率与心电图改变的联系。方法选取2014年12月~2015年10月在我院实行治疗的46例急性心肌梗死患者作为研究对象,分析其心电图改变的情况,并观察其心律失常的发生情况与发生类型。结果经检测,在46例患者中出现心电图典型表现患者34例(73.91%),非典型表现患者12例(26.09%),典型表现患者比例高于非典型患者比例,差异有统计学意义(P<0.05)。而在ST段抬高患者中出现心律失常患者20例(58.82%);在非ST段抬高患者中出现心律失常患者3例(25.00%),ST段抬高患者心律失常发生率高于非ST段抬高患者,差异有统计学意义(P<0.05)。在患者心律失常发生类型方面,主要发生仿型与结性早搏、阵发性窦性心动过速与过缓等心律失常现象,但各类型心律失常发生率对比,差异无统计学意义(P>0.05)。结论 ST段抬高是急性心肌梗死患者的心电图主要特征,在此范围内的患者,其心律失常发生率要远远高于非ST段抬高患者。
Objective To investigate the relationship between the incidence of arrhythmia and ECG changes in patients with acute myocardial infarction. Methods Forty-six patients with acute myocardial infarction who were treated in our hospital from December 2014 to October 2015 were selected as the research object to analyze the changes of electrocardiogram and to observe the occurrence and type of arrhythmia. RESULTS: Of the 46 patients, 34 (73.91%) showed typical electrocardiographic findings and 12 (26.09%) showed typical patterns of electrocardiogram. The proportion of patients with typical manifestations was higher than that of atypical patients (P <0.05). 20 cases (58.82%) had arrhythmia in patients with ST segment elevation, 3 cases (25.00%) had arrhythmia in non-ST segment elevation patients, and the incidence of arrhythmia in ST segment elevation patients was higher than that ST-segment elevation in patients with significant difference (P <0.05). In the type of patients with arrhythmia, the main occurrence of copy and premature beats, paroxysmal sinus tachycardia and bradycardia and other arrhythmia, but the incidence of various types of arrhythmia, the difference was not statistically significant (P> 0.05). Conclusion ST segment elevation is the main feature of electrocardiogram in patients with acute myocardial infarction. The incidence of arrhythmia in patients within this range is much higher than that of non-ST segment elevation patients.
