Abstract

Objectives: To describe some clinical and paraclinical characteristics of supraventricular tachycardia in children at the Emergency and Anti-toxic Department. Research subjects and methods: A prospective cross-sectional and retrospective description of 50 patients diagnosed with Supraventricular tachycardia (SVT) at the Emergency and Anti-toxic Department, Vietnam National Children's Hospital. Results: The age group ≥ 1 year old accounted for the majority (76%). The most common functional symptoms in children < 5 years old were irritability and poor appetite (accounting for 64%), while in the group of children ≥ 5 years old with palpitations (76%) with the difference between 2 groups had a statistical significance (p<0.05). Regarding physical symptoms: acute heart failure, acute respiratory failure, hepatomegaly are mainly seen in the group of < 1 year old. On electrocardiogram, most cases have narrow QRS (94%) and average QRS time is 71.2 ± 21ms. Serum NT-ProBNP levels were mostly increased, accounting for 89.2% of cases. Decreased heart function accounted for 18.2% of cases and there was a difference between the 2 groups with shock and without shock (p<0.05). Conclusion: The clinical symptoms of supraventricular tachycardia in children are varied, non-specific and depend on age. Most patients have a narrow QRS complex on the electrocardiogram and there is an increase in NT-ProBNP levels in patients with supraventricular tachycardia.
