动态心电图与常规心电图对冠心病患者心律失常的诊断价值比较

目的：探讨常规心电图与动态心电图在诊断冠心病心律失常疾病方面的应用价值。方法选取我院心内科收治的冠心病患者60例，均符合冠心病诊断标准，先用常规心电图对所有患者进行检查；然后采用动态心电图系统再次进行检查，24 h监测患者的心率变化。采用计算机分析比较两种诊断方法的检查结果。结果常规心电图检测心律失常阳性34例（56．67％），低于动态心电图的检出率71．67％（43／60），差异有统计学意义（P＜0．05）。动态心电图对房性早搏二、三联律，室性早搏二、三联律，房性早搏成对，室性早搏成对和短阵室上速的检出率高于常规心电图，差异有统计学意义（P＜0．05）。结论与常规心电图相比，动态心电图具有明显优势，它可检测出患者任一时间点的冠脉缺血情况、心律失常发作时间和频率，能够更准确、更精细地监测患者心电信号，值得在临床中广泛应用。

Comparison between ambulatory electrocardiography and routine electrocardiogram in diag-nosing arrhythmia for patients with coronary heart disease

Objective To discuss the clinical values of ambulatory electrocardiography （ AECG） and routine electrocardiogram （ ECG ） in diagnosing arrhythmia in patients with coronary heart disease.Methods We selected 60 patients diagnosed with coronary heart disease in the department of cardiology in our hospital .They were examined first by routine ECG , and then AECG in order to monitor the changes of their heart rates for 24 hours.The examination results in the two diagnostic methods were comparatively analyzed by computer .Results There were 34 cases of arrhythmia de-tected by routine ECG , accounting for 56 .67%, lower than the detection rate of 71 .67%（ 43/60 ） by AECG, and the difference was statistically significant （P〈0.05）.By AECG, the detection rates of atrial premature beats bigeminy/trigeminy, premature ventricular contraction bigeminy/trigeminy, pairing of atrial premature beats , pairing of premature ventricular contraction , and paroxysmal su-praventricular tachycardia were higher than those by routine ECG , with statistically significant differ-ences（P〈0.05）.Conclusion AECG is superior to routine ECG because the former can detect coronary ischemia at any time point as well as the duration and frequency of arrhythmia , and is also capable of monitoring electrocardiosignals more accurately and more finely .AECG is worthy of being promoted clinically .
