Abstract

Objectives: To describe the clinical and paraclinical characteristics of pediatric supraventricular tarchycardia and ventricular tachycardia at Vietnam National Children’s Hospital. Subjects and Method: Descritive study of 89 children who developed tachycardia at Vietnam National Children’s Hospital from March 2019 to June 2020. Results: Among 89 children: 71 children had SVT (79.8%) and 18 children (20,2%) had VT. Children aged less than 12 months accouted for 42.7%. 36/89 children had comorbidities, of which 19/89 children had congenital heart disease, accounted for 21.3%. Comparing to VT, SVT was lesser circulation failure (18.3% vs 55.6%; p = 0,003), higher heart rate (238.1 ± 31.0 vs 209.6 ± 34.0; p < 0.001), lesser reduced left ventricular ejection fraction (LVEF) (18.3% so với 44.4%, p < 0.029), shorter QRS period (77.9 ± 23.0 vs 131.4 ± 23.6; p < 0.001). Conclusion: Comparing to VT, SVT was higher heart rate, lesser circulatory failure, more common in younger children. VT accounted for high circulation failure proportion and was common in older children.
