探讨动态心电图在冠心病心律失常诊断中的应用价值。

回顾性分析2016年3月至2018年3月胶州市人民医院收治的70例冠心病患者的临床资料，所有患者均经冠状动脉造影确诊，检查前均接受常规心电图与动态心电图检查，对比两种检查方式对心肌缺血与心律失常(房性心律失常、室性心律失常、房室传导阻滞、矩阵室上速等)的检出率。

70例冠心病患者中，常规心电图检查显示心肌缺血阳性检出率为80.00%(56/70)，低于动态心电图检查92.86%(65/70)，差异有统计学意义(P<0.05)。动态心电图房性心律失常、室性心律失常、房室传导阻滞、矩阵室上速阳性检出率高于常规心电图，差异有统计学意义(P<0.05)。

动态心电图可提高冠心病心律失常的检出率，为疾病评估与预后判断提供丰富而详细的影像与数据。

To investigate the clinical application value of dynamic electrocardiogram in coronary heart disease with arrhythmia.

The clinical data of 70 patients with coronary heart disease admitted to Jiaozhou People's Hospital from March 2016 to March 2018 were retrospectively analyzed. All patients were diagnosed by coronary angiography and underwent routine electrocardiogram (ECG) and dynamic electrocardiogram (DECG) before coronary angiography examination. The detection rate of two methods were compared for myocardial ischemia and arrhythmia, such as atrial arrhythmia, ventricular arrhythmia, atrioventricular block, matrix supraventricular tachycardia, etc.

In 70 patients with coronary heart disease, the positive detection rate of myocardial ischemia was 80.00% (56/70) by routine electrocardiogram, which was lower than that by dynamic electrocardiogram with 92.86% (65/70), and the difference was statistically significant (P<0.05). The positive detection rates of atrial arrhythmia, ventricular arrhythmia, atrioventricular block and matrix supraventricular tachycardia in dynamic electrocardiogram were higher than those in conventional electrocardiogram (P<0.05).

Dynamic electrocardiogram can improve the detection rate of coronary heart disease combined with arrhythmia, and provide rich and detailed images and data for disease assessment and prognosis judgment.
