摘 要:目的:分析ST段抬高型急性心梗并J波综合征患者的心电图特点。方法:回顾性分析2018年10月~2020年2月65例ST段抬高型急性心梗患者的临床资料,其中21例合并J波综合征(观察组),44例为单纯ST段抬高型急性心梗(对照组),比较两组患者临床基础资料和心电图参数。结果:两组患者的年龄、性别、慢性病史、吸烟、左室射血分数、≥30s房速/房颤比较,无统计学意义,P>0.05;两组患者的持续性室速/室颤率以及病死率比较,观察组患者的持续性室速/室颤率(28.60%)、病死率(28.60%)均明显高于对照组的9.10%、6.80%,P<0.05;观察组的QT间期的最小值为(355.50±47.50)ms、QT间期的最大值为(409.50±51.50)ms、离散度为50.50±19.50,对照组分别为(363.50±44.50)ms、(450.50±40.50)ms、40.50±15.50,两组的QT间期的最大值比较无统计学意义,P>0.05。但观察组的QT间期的最小值明显小于对照组,离散度明显高于对照组,P<0.05。结论:ST段抬高型急性心梗并J波综合征与单纯ST段抬高型急性心梗的心电图存在差异,表现为QT间期离散度增大,发生持续性室速/室颤率和死亡的风险增高,需加以警惕,以提高患者的安全性。Objective:To analyze the electrocardiogram characteristics of patients with ST-segment elevation acute myocardial infarction and J wave syndrome.Methods:The clinical data of 65 patients with ST-segment elevation acute myocardial infarction from October 2018 to February 2020 were retrospectively analyzed.Among them,21 cases were combined with J wave syndrome(study group),and 44 cases were pure ST-segment elevation.Type acute myocardial infarction(control group),compare the basic clinical data and electrocardiogram parameters of the two groups of patients.Results:The comparison of age,gender,chronic medical history,smoking,left ventricular ejection fraction,≥30s atrial tachycardia/atrial fibrillation of the two groups of patients was nearly insignificant P>0.05;Comparing the persistent ventricular tachycardia/ventricular fibrillation rate and the fatality rate of the two groups of patients,the persistent ventricular tachycardia/ventricular fibrillation rate(28.60%)and the fatality rate(28.60%)of the observation group were significantly higher than those of the control group(9.10%,9.10%).6.80%,P<0.05;The minimum QT interval of the observation group was(355.50±47.50)ms,the maximum QT interval was(409.50±51.50)ms,and the dispersion was 50.50±19.50,while the control group was(363.50±44.50)ms,(450.50±40.50)ms,40.50±15.50,the maximum value of QT interval between the two groups was not statistically significant,P>0.05.However,the minimum QT interval of the study group was significantly smaller than that of the control group,and the dispersion was significantly higher than that of the control group,P<0.05.Conclusion:The electrocardiogram of ST-segment elevation acute myocardial infarction with J wave syndrome is different from that of ST-segment elevation acute myocardial infarction,which is manifested by increased QT interval dispersion,persistent ventricular tachycardia/ventricular fibrillation rate and the risk of death is increased,and vigilance is needed to improve the safety of patients.
