目的：探究动态心电图对无症状性心肌缺血的临床诊断价值。方法整群选取该院2013年11月—2014年11月收治的130例冠心病患者为研究对象,参照Cohn分类标准法,分别将分为A、B两组,A组为无症状性心肌缺血Ⅰ型；B组为心绞痛并伴有无症状性心肌缺血Ⅲ型,两组患者均采用动态心电图连续监测24 h后,分析ST段的位移指标。结果A、B两组无症状心肌缺血的ST段下移速度及下移持续时间在早8：00至晚6：00与晚6：00至早6：00之间的发作频率之比为1.92：1(656阵次,341阵次),P<0.05；130例患者心肌缺血次数共计1220次,其中发生心肌缺血118例(90.77%),A组无症状心肌缺血997次,明显高于B组有症状心急缺血次数(P<0.05)；A组无症状性心肌缺血患者ST段下移心率及平均心率与B组有症状性心肌缺血相比,前者明显小于后者(P<0.05),差异有统计学意义。结论动态心电图诊断无症状性心肌缺血准确性与敏感性较高,对防治冠心病意义重大,值得临床推广使用。

Objective To explore the diagnostic value of Holter monitoring silent myocardial ischemia. Methods Hospital from November 2013 to November 2014 were treated 130 cases of coronary heart disease patients for the study, referring to Cohn clas-sification method, respectively, will be divided into A, B groups, A group of silent myocardial ischemia type “Ⅰ”,group B with angina and silent myocardial ischemia“Ⅲ”type, two patients were treated with continuous ambulatory ECG monitoring after 24h, ST segment analysis displacement indicators. Results ST segment depression rate A, B groups of asymptomatic myocardial is-chemia and seizure frequency ratio between 8:00 am to 6:00 pm and 6:00 pm to 6:00 nights down duration 1.92: 1 (656 array times, 341 times the array), (P<0.05). 130 patients with a total of 1220 times the number of myocardial ischemia, myocardial is-chemia and 118 cases (90.77%) of which occurred, A group of silent myocardial ischemia in 997 times significantly higher than that in group B with symptoms of ischemic times impatient (P<0.05). ST segment A group of silent myocardial ischemia in patients with heart rate and average heart rate down and group B compared with symptomatic myocardial ischemia, significantly less than the former The latter (P<0.05), with statistical significance. Conclusion Holter diagnostic accuracy of silent myocardial ischemia and high sensitivity, the prevention of coronary heart disease is of great significance, worthy of clinical use.
