OBJECTIVE: Numerous restrictions, which are imposed on children with arrhythmia, influence their quality of life (QoL) and may have a negative impact on their further development. Ablation is a highly successful treatment leaving patients free from arrhythmia and other related limitations. There are very few studies evaluating the influence of ablation on the QoL in children with arrhythmia, based on small groups of patients. The aim of this study was to evaluate the impact of ablation on the QoL in children with supraventricular tachycardia (SVT).

PATIENTS AND METHODS: We included 122 children with SVT who underwent a successful ablation. The Qol was assessed before and after the ablation, using the WHOQOL-BREF and the Pediatric Arrhythmia Related Score (PARS) – a specific questionnaire developed by the authors.

RESULTS: Six months after the ablation, WHOQOL-BREF showed a significant improvement in the QoL in the physical (Phd) (p < 0.0001), psychological (Psd) (p = 0.0014) and social relationships (SRD) (p = 0.0165) domains. PARS showed a significant improvement in the QoL in the Phd (p < 0.0001), Psd (p = 0.0307) and medical satisfaction domains (Msd) (p < 0.0001). No improvement in Psd was revealed in children who had been off medications before the ablation. In the youngest children, a significant improvement was observed in all the measured domains in both questionnaires (p < 0.05), while in older children the greatest improvement after the ablation was noted in the area of physical functioning.

CONCLUSIONS: Ablation in children with SVT significantly improved general satisfaction with health and with the QoL and had a positive impact on QoL scores. The youngest patients and those on antiarrhythmic medication before the ablation, benefit most from the procedure.
