摘要
目的:探讨动态心电图在无症状心肌缺血中诊断价值及临床特点。方法:选取2015年2月~2016年2月我院诊治冠状动脉粥样硬化性心脏病患者108例为研究对象,采用12导联动态心电图进行监测,并在监测同时告知受检者应记录完整动态心电图生活日记,统计心肌缺血检出率、有症状心肌缺血检出率、无症状心肌缺血检出率及心肌缺血ST改变发作次数、不同性别不同时间段心肌缺血发生次数。结果:108例冠心病患者检出心肌缺血83例,心肌缺血发生率为76.85%。其中有症状心肌缺血患者16例,占19.28%,无症状心肌缺血患者67例,占80.72%,无症状心肌缺血检出率显著高于有症状心肌缺血检出率,比较有统计学意义(P<0.05)83例心肌缺血患者共检出ST段改变369次,16例有症状心肌缺血患者发生ST段改变52次,占14.09%;67例无症状心肌缺血患者ST段改变次数317次,占85.91%;无症状心肌缺血患者ST段改变检出率显著高于有症状心肌缺血患者,比较有统计学意义(P<0.05)。无症状心肌缺血患者ST段改变317次,其中6:01~12:00时间段发生次数最多,占51.10%,其次为18:01~24:00时间段,占33.12%;显著高于12:01~18:00时间段和24:01~06:00时间段,比较有统计学意义(P<0.05)。男性在6:01~12:00时间段发生次数显著多于女性,比较有统计学意义(P<0.05)。结论:动态心电图能提高无症状心肌缺血临床检出率,并对不同性别心肌缺血患者发生时间、特点进行系统性分析。
Objective： To investigate the value of dynamic electrocardiogram in the diagnosis of silent myocardial ischemia and its clinical characteristics. Methods： From February 2015 - February 2016 year in our hospital diagnosis and treatment of patients with coronary heart disease in 108 cases as the research object, using the 12 lead Hoher monitoring, and monitoring of subjects should be told in a complete record of Holter diary, statistical myocardial ischemia detection rate, symptomatic myocardial ischemia detection rate, detection rate of asymptomatic myocardial ischemia ST changes and myocardial ischemia episodes, different sex and different time of occurrence of myocardial ischemia. Results： 108 cases of coronary heart disease were detected in 83 cases of myocardial isch- emia, the incidence rate of myocardial ischemia was 76.85%. There are 16 cases of patients with myocardial ischemia symptoms ac- counted for 19.28% of patients with silent myocardial ischemia in 67 cases, accounting for 80.72%, significantly higher than that of as- ymptomatic myocardial ischemia detection rate of symptomatic myocardial ischemia detection rate was statistically significant （P 〈 0.05） 83 cases of patients with myocardial ischemia were detected in ST segment change 369 times, in 16 cases the symptoms of myo- cardial ischemia in patients with ST segment change 52 times, accounting for 14.09%; 67 cases of asymptomatic myocardial ischemia in patients with ST segment changes the number of 317 times, accounting for 85.91%; asymptomatic myocardial ischemia in patients with ST segment changes in patients with myocardial ischemia symptoms detection rate was significantly higher, compared with statis- tical significance （P 〈 0.05）. No symptoms of myocardial ischemia in patients with ST segment change 317 times, the 6：01-12：00 time period occurred most frequently, accounting for 51.10%, followed by 18：01-24：00 time, accounted for 33.12%; was significantly higher than that in 12：01-18：00 period and 24：01-06：00
