Abstract
Objective To study the application of dynamic electrocardiogram (ECG) in the clinical diagnosis of coronary artery disease. Methods 82 patients with suspected coronary heart disease were randomly divided into two groups. 41 cases of the observation group received dynamic ECG diagnosis, while 41 cases of the control group received routine ECG. The detection rates and ST segment depression duration were compared between two groups. Results 464 times of ST segment depression duration were found in the observation group, including 392 times of SMI attack, and 72 times of symptomatic ischemic attack, all of the above were significantly higher than those of the control group (P<0.05). The SMI duration and symptomatic myocardial ischemia duration of the observation group were (14.6±3.5) min/time and (31.2±9.8) min/time respectively, significantly higher than those of the control group (P<0.05). According to ST segment depression measured by the number of SMI, the observation group had 198 times from 6:00 to 12:00, 84 times from 12:00 to 18:00, 57 times from 18:00 to 24:00, and 47 times from 0:00 to 6:00, all were significantly higher than those of the control group (P<0.05). Conclusions In the clinical diagnosis of coronary artery disease, dynamic ECG can improve the detection rate with high safety, which is worthy of clinical application.关键词
