ABSTRACT

Objective To investigate the clinical value of dynamic electrocardiogram (ECG),heart color Doppler ultrasound in the diagnosis of the paroxysmal atrial fibrillation .Methods A total of 130 cases of suspected paroxysmal atrial fibrillation in Zhejiang Rongjun Hospital were included in the study .The patients received routine ECG,dynamic ECG,heart color Doppler ultrasound examination ,the examination results were analyzed .The clinical comprehensive diagnosis was used as the diagnostic reference ,the diagnostic sensitivity,specificity,accuracy of three methods in the diagnosis of paroxysmal atrial fibrillation were compared .And the consistency coefficient of three examination results and clinical diagnosis of paroxysmal atrial fibrillation was compared .Results The sensitivity, specificity and accuracy of the heart color Doppler ultrasound in diagnosis of paroxysmal atrial fibrillation were 94.23%,96.15%,94.61%,respectively,which of the dynamic ECG were 97.12%,100.00%,97.69%,respectively, which of the routine ECG were 83.65%,76.92%,82.31%,respectively.The diagnostic sensitivity ,specificity and accuracy of the heart color Doppler ultrasound were higher than those of the routine ECG (χ2＝5.915,4.127,9.646, all P＜0.05).The diagnostic sensitivity,specificity and accuracy of the dynamic ECG were also higher than those of the routine ECG(χ2＝10.843,6.783,17.094,all P＜0.05),the differences of the heart color Doppler ultrasound and dynamic ECG were not statistically significant (χ2＝1.045,1.020,1.664,all P＞0.05).The consistency coeffi－cient of the heart color Doppler ultrasound ,dynamic ECG with the results of clinical diagnosis were 0.735,0.762, respectively,which was higher than that of the routine ECG .Conclusion Dynamic ECG,heart color Doppler ultra－sound in the diagnosis of paroxysmal atrial fibrillation has higher accuracy ,sensitivity and specificity,which can be used as the main means of diagnosis of paroxysmal atrial fibrillation .
