Abstract

Abstract:

Objective

To compare the diagnostic value of dynamic electrocardiogram (dECG) and color Doppler ultrasonography for arrhythmia and myocardial ischemia.

Methods

Fifty patients treated in Zhanzhou People’s Hospital from June of 2015 to December of 2016 were enrolled in the study. dECG, color Doppler ultrasonography and coronary angiography were used. The detectable rates of dECG and color Doppler ultrasonography for arrhythmia and myocardial ischemia were compared. Using coronary angiography as the gold standard, the diagnostic value of dECG and color Doppler ultrasonography for myocardial ischemia was compared.

Results

The detectable rates of dECG and color Doppler ultrasonography for atrial premature beats were 62.0%(31/50) and 40.0%(20/50) respectively. The detectable rate of dECG for atrial premature beats was higher than color Doppler ultrasonography, and the difference was statistically significant (P<0.05). The detectable rates of dECG and color Doppler ultrasonography for myocardial ischemia were 85.7%(36/42) and 66.7%(28/42) respectively. The detectable rate of dECG for myocardial ischemia was higher than color Doppler ultrasonography, and the difference was statistically significant (P<0.05). The sensitivity and accuracy of dECG in diagnosing myocardial ischemia were higher than color Doppler ultrasonography.

Conclusion

The detectable rates of dECG for arrhythmia and myocardial ischemia are higher than color Doppler ultrasonography, and the diagnostic value is higher.
