目的:研究动态心电图(DCG)诊断小儿心律失常及心率变异性(HVR)的临床价值。方法:560例患者均进行常规心电图和动态心电图的检查,由两组专业人员分别对心电图(ECG)和动态心电图(DCG)的检查结果进行(评价),比较两种检查手段的不同类型的心律失常的诊出率;评价不同类型心律失常的HVR。结果:ECG对各型心律失常的总诊出率为25.00%,对不同类型心率失常的诊出率分别为5.71%、1.43%、9.29%、6.43%和2.14%;DCG总诊出率为62.85%,对不同类型心率失常的诊出率分别为16.43%、6.43%、17.86%、14.29%和7.86%,二者具有统计学差异(P<0.05)。不同类型的心律失常的HVR不同,其中室性心动过速和室性期前收缩的各项指标均明显低于其他类型(P<0.05)。结论:DCG对不同心律失常的诊出率明显高于ECG,并能有效反应不同类型心率失常的HVR,在小儿心律失常的诊断中具有一定的临床价值。
Objective: To study the clinical value of dynamic electrocardiogram (DCG) in diagnosing pediatric arrhythmia and heart rate variability (HVR). Methods: Five hundred and fifty-six patients underwent routine electrocardiogram and ambulatory electrocardiogram examinations. ECG and ambulatory electrocardiogram (DCG) examinations were performed by two groups of professionals respectively. The different types of heart rhythm were compared between the two examinations Outpatient diagnosis rate; Evaluation of different types of arrhythmia HVR. Results: The total diagnosis rate of ECG was 25.00% for all kinds of arrhythmias and 5.71%, 1.43%, 9.29%, 6.43% and 2.14% for different types of arrhythmia respectively. The total diagnosis rate of DCG was 62.85 %. The diagnostic rates for different types of arrhythmia were 16.43%, 6.43%, 17.86%, 14.29% and 7.86%, respectively, with statistical significance (P <0.05). HVR of different types of arrhythmia is different, including ventricular tachycardia and ventricular contraction were significantly lower than the other indicators (P <0.05). Conclusion: The diagnosis rate of DCG to different arrhythmias is obviously higher than that of ECG, and can effectively respond to HVR of different types of arrhythmia. It has some clinical value in the diagnosis of arrhythmia in children.
