中文摘要：

目的：分析冠心病（ Coronary heart disease, CHD）心律失常（Arrhythmia）患者诊断中常规心电图（EcG）和动态心电图（DCG）两种诊断方式效果。方法：选取我院收治的CHD患者84例作为研究对象，分别使用ECG和DCG两种方式进行诊断，判断2种方法冠心病检测阳性率、心律失常检出率的情况。结果：动态组检测的阳性率为63．10％（53例），常规组为58．33％（49例），数据差异无统计学意义P〉0．05；8项心律失常指标中房性／室上性早搏早发、方式传导阻滞等检出率差异无统计学意义，P〉0．05；其余5项检出率差异显著，P〈0．05。结论：冠心病心律失常患者的诊断时采用动态心电图在冠心痛诊断阳性率和心律失常检出率方面均有一定的优势。

英文摘要：

Objective： To analyze the effects of routine electrocardiogram （ECG） and dynamic electrocardiogram （DCG） in the diagnosis of coronary heart disease （Arrhythmia）. Methods： From our hospital, 84 cases of CHD patients treated between June 2013 and June 2014 were taken as the research objects. They were respectively given ECG and DCG for diagnosis. Access the detection rate of two methods for coronary artery disease and arrhythmia. Results： The positive rate was 63.10% in dynamic detection group （53 cases） and 58.33% in conventional detection group （49 cases）, but there was no significant difference （P 〉 0.05）. Among the eight arrhythmia indexes, detection positive rate of atrial/ventricular premature beats, conduction block had no significant difference （P 〉 0.05）, but the detection positive rate of the rest five indexes had significant difference （P 〈 0.05）. Conclusion： The dynamic electrocardiogram has certain advantages in the diagnosis of coronary heart disease and detection rate of arrhythmia. So it is worthy of popularization and application.
