ABSTRACT
Objective:
To explore diagnostic value of dynamic electrocardiogram (DCG) on coronary artery disease.Methods:
A total of 100 inpatients with “angina pectoris” history from our hospital were enrolled and received 24h DCG measurement. The DCG examination results were compared with those of coronary angiography (CAG) and analyzed then.Results:
Among the 100 patients, there were 85 patients with positive DCG, including 70 cases with positive CAG and 15 cases with negative CAG; and 15 patients with normal (negative) DCG, including 10 cases with negative CAG and five cases with positive CAG. With CAG as golden standard, sensitivity, specificity, positive predictive value (accuracy) and negative predictive value of DCG in diagnosis of coronary heart disease were 93.3%, 40.0%, 82.4% and 66.7% respectively. Partial patients had “angina pectoris”, no stenosis in CAG but there’s slow blood flow.Conclusion:
Dynamic electrocardiography is one of important measuring methods diagnosing coronary heart disease. It is simple, practical, safe, economic and appropriate for wide application in clinic, but its specificity is just 40.0%, so coronary heart disease cannot be excluded in negative patients.
