目的探讨冠心病心律失常应用12导联动态心电图监测的价值。方法选取2014年7月—2015年7月162例住院及门诊患者,均采取12导联动态心电图及常规心电图(ECG),观察冠心病心律失常的检出情况及ST-T异常检出情况。结果 162例患者经12导联动态心电图24 h监测的检出率为71.60%,常规心电图监测的检出率为34.57%,常规ECG漏检率为51.72%;12导联动态心电图监测,ST-T异常者58例(35.80%),常规心电图监测ST-T异常者22例(13.58%),常规漏诊ST-T异常患者有36例(62.07%)。结论 12导联DCG诊断冠心病心律失常敏感性、有效性、准确性均较高,值得临床应用推广。
Objective To investigate the value of 12-lead ambulatory electrocardiogram monitoring in patients with coronary heart disease and arrhythmia. Methods From July 2014 to July 2015, 162 inpatients and outpatients in our hospital were enrolled in this study. Both 12-lead ambulatory electrocardiogram and routine electrocardiogram (ECG) were performed to observe the detection of cardiac arrhythmia and the detection of ST-T abnormalities. Results 162 cases of patients by 12-lead Holter monitoring 24 h detection rate was 71.60%, conventional ECG detection rate was 34.57%, conventional ECG missed detection rate was 51.72%; 12-lead ambulatory ECG monitoring, ST- T abnormalities in 58 cases (35.80%), conventional electrocardiogram monitoring of 22 cases of abnormal ST-T (13.58%), routine missed diagnosis of ST-T abnormalities in 36 patients (62.07%). Conclusions The sensitivity, validity and accuracy of 12-lead DCG in the diagnosis of coronary heart disease are worthy of clinical application.
