左心室肥厚并急性心肌梗死患者室性电风暴心电图特征及对预后的影响

Electrocardiogram characteristics of ventricular electrical storm in patients with left ventricular hypertrophy and acute myocardial infarction and its influence on prognosis

目的:研究左心室肥厚并急性心肌梗死患者室性电风暴心电图特征及对预后的影响。方法:选择2018年1月至2019年1月就诊于青海红十字医院的左心室肥厚并急性心肌梗死室性电风暴患者100例作为观察组,另选取无左心室肥厚的急性心肌梗死室性电风暴患者作为对照组,两组患者均进行心电图检查以及持续心电监护,对心电图特征和患者预后进行分析,比较两组患者ST段抬高导联数、QTc间期、对应导联ST段下移发生率、冠脉病变支数及并发症发生率。结果:观察组ST段抬高导联数(4.17±1.07),QTc间期(431.0±13.2)mm、对应导联ST段下移发生率(36.0%)与对照组比较,差异具有统计学意义(P<0.05)。观察组冠脉病变支数(1支49例、2支30例、3支21例)与对照组(1支7例、2支13例、3支10例)比较,差异具有统计学意义(P<0.01)。观察组并发症发生率高于对照组(7.0%比2.0%,P<0.05)。结论:左心室肥厚并急性心肌梗死室性电风暴患者心电图多项指标发生异常,对患者预后具有预测价值。

Objective:To study the electrocardiogram characteristics of ventricular electrical storm in patients with left ventricular hypertrophy and acute myocardial infarction and its influence on prognosis.Methods:One hundred patients with left ventricular hypertrophy(LVH)and acute myocardial infarction(AMI)in Qinghai Red Cross Hospital from January 2018 to January 2019 were enrolled in the observation group,100 patients without LVH in the control group.All patients underwent electrocardiography(ECG)examination and continuous ECG monitoring.Electrocardiogram characteristics and prognosis were analyzed.The number of ST segment elevation leads,QTc interval,the incidence of ST segment depression of corresponding leads,the number of coronary lesions and the incidence of complications were compared between the two groups.Results:There was significant difference in the number of ST segment elevation leads,QTc interval,and the incidence of ST segment depression of corresponding leads between the two groups(P<0.05).There was significant difference in the number of coronary lesions between the two groups(P<0.01).The incidence rate of complications in the observation group was higher than that in the control group(7.0%vs.2.0%,P<0.05).Conclusion:The multiple electrocardiogram indexes of the patients with LVH and AMI are abnormal,which can predict the prognosis of the patients.
