中文摘要：目的分析冠心病无症状性心肌缺血采取动态心电图进行诊断的效果.方法选取200例冠心病心肌缺血患者为研究对象,均进行动态心电图连续检查.将冠状动脉造影检查作为诊断的金标准,分析动态心电图对冠心病无症状性心肌缺血的诊断效能;分析动态心电图的诊断结果.结果 200 例冠心病心肌缺血患者,经冠状动脉造影诊断显示无症状性心肌缺血患者 113 例,有症状性心肌缺血患者87 例.动态心电图诊断显示无症状性心肌缺血患者 105 例,有症状性心肌缺血患者 95 例.动态心电图诊断冠心病无症状性心肌缺血的漏诊率为 14.2%(16/113),误诊率为 9.2%(8/87),灵敏度为 85.8%(97/113),特异度为90.8%(79/87).200例冠心病心肌缺血患者通过动态心电图诊断,有症状性心肌缺血患者95例、占比 47.5%(95/200),24 h内共发作 182 次心肌缺血,其中 0:00～5:00 发作 67 次、占比 36.8%,6:00～24:00发作 115 次、占比 63.2%.无症状性心肌缺血患者 105 例、占比 52.5%(105/200),24 h内共发作 278 次心肌缺血,其中 0:00～5:00 发作 63 次、占比 22.7%,6:00～24:00 发作 215 次、占比 77.3%.无症状性心肌缺血患者ST段下移持续时间为(13.5±4.6)min/次,有症状性心肌缺血患者ST段下移持续时间为(30.1±10.9)min/次,无症状性心肌缺血患者ST段下移持续时间短于有症状性心肌缺血患者,差异具有统计学意义(P<0.05).结论对于冠心病无症状性心肌缺血采取动态心电图进行诊断的临床价值高,可以显著提升检出率,对于评估冠心病无症状性心肌缺血存在非常重要的意义.

外文标题：Analysis of clinical effect of Holter electrocardiogram in diagnosis of asymptomatic myocardial ischemia in coronary heart disease

外文摘要：Objective To analyze the effect of Holter electrocardiogram in the diagnosis of asymptomatic myocardial ischemia in coronary heart disease.Methods 200 coronary heart disease patients with asymptomatic myocardial ischemia were selected as the study subjects.Using coronary angiography as the gold standard,the diagnostic efficiency of Holter electrocardiogram for asymptomatic myocardial ischemia in coronary heart disease was analyzed.The diagnostic results of Holter electrocardiogram were analyzed.Results Among 200 patients with coronary heart disease,113 patients had asymptomatic myocardial ischemia by coronary angiography and 87 patients had symptomatic myocardial ischemia.Among 200 patients with coronary heart disease,95 patients with symptomatic myocardial ischemia,accounting for 47.5%(95/200),with 82 episodes of myocardial ischemia within 24 h,of which 67 episodes occurred between 0:00 and 5:00 in the morning,accounting for 36.8%,and 115 episodes occurred between 6:00 and 24:00,accounting for 63.2%.105 patients with asymptomatic myocardial ischemia,accounting for 52.5%(105/200),with 278 episodes of myocardial ischemia within 24 h,of which 63 episodes occurred between 0:00 and 5:00 in the morning,accounting for 22.7%,and 215 episodes occurred between 6:00 and 24:00,accounting for 77.3%.The duration of ST segment depression was(13.5±4.6)min/time in asymptomatic myocardial ischemia patients,and(30.1±10.9)min/time in symptomatic myocardial ischemia patients;the duration of ST segment depression in asymptomatic myocardial ischemia patients was shorter than that in symptomatic myocardial ischemia patients,and the difference was statistically significant(P<0.05).Conclusion The application of Holter electrocardiogram in the diagnosis of asymptomatic myocardial ischemia in coronary heart disease has high clinical value,which can significantly improve the detection rate,and is of great significance for the evaluation of asymptomatic myocardial ischemia in coronary heart disease.
