Evaluation of medical and psychological parameters of quality of life in supraventricular tachyarrhythmia children. A comparison with healthy children.

Introduction: There are only a few available studies evaluating quality of life (QoL) in pediatric patients with cardiac arrhythmia. The aim of the study was to evaluate medical and psychological parameters of the QoL in children with a diagnosed supraventricular tachyarrhythmia (SVT) and to compare the obtained data with a group of healthy children (HC).

Material And Methods: Inclusion criteria: children aged 7-18 with SVT, treated at Poznan University of Medical Sciences, Department of Pediatric Cardiology. The evaluation tools were the WHOQOL-BREF instrument and a questionnaire related to the patient's feelings and observations concerning arrhythmia (Pediatric Arrhythmia Related Score - PARS), developed by the authors and adjusted to the group of arrhythmia patients.

Results: The study included 180 SVT children and 83 HC. On the basis of WHOQOL-BREF the SVT group was found to have lower assessment values of QoL within the physical domain (Phd) (mean ± SD: 65.7 ±15.8 vs. 81.6 ±12.8; < 0.0001) and psychological domain (Psd) (mean ± SD: 75.8 ±15.2 vs. 81.3 ±14.1; < 0.005). No significant differences were found within the social relationships domain or the environment domain. On the basis of PARS in the SVT group the patients reported significantly increased symptoms within Phd (mean ± SD: 2.3 ±0.7 vs. 1.6 ± 0.3; < 0.0001) as well as increased negative feelings within Psd (mean ± SD: 2.3 ±0.7 vs. 2.1 ± 0.6; < 0.005).

Conclusions: Medical and psychological parameters of the QoL in SVT children are significantly lower in comparison with HC. A diagnosis of SVT has no influence on the social and environmental areas of QoL. The PARS appears to be a useful tool to supplement the generic questionnaire for QoL evaluation in SVT children.
