ABSTRACT
Objective To compare the application value of routine electrocardiogram and dynamic electrocardiogram in the diagnosis of arrhythmia and heart rate variability in children.Methods In our hospital,pediatric arrhythmia patients were given routine electrocardiogram and dynamic electrocardiogram.The relationship between arrhythmia and heart rate variability in children was analyzed.Results Supraventricular tachycardia (13.33%),ventricular tachycardia(5.56%),premature ventricular contraction (21.11%),premature atrial contraction (14.44%),block (12.22%) in the dynamic electrocardiogram were significantly better than the conventional electrocardiogram,and the differences were statistically significant x2=11.93,4.56,9.22,10.74,11.55,all P<0.05).There were significant differences in the heart rate variability between ventricular arrhythmias and non-ventricular arrhythmias in children[(78.85±0.88),(4.68±2.43),(24.78±2.56),(21.66±0.94), t=10.88,11.79,9.84,9.92,all P<0.05].Conclusion Compared with routine electrocardiogram, dynamic electrocardiogram has better diagnostic value for pediatric arrhythmia of ventricular tachycardia.The detection rate of ventricular tachycardia,ventricular tachycardia,premature ventricular contraction,atrial premature contraction,conduction block and other arrhythmias are obviously superior.And dynamic ECG measurement of heart rate variability is helpful to assess the severity of the disease.
