Patients' Perspective on Radiofrequency Catheter Ablation of AVRT and AVNRT (PPRA)
Atrioventricular nodal reciprocating tachycardia (AVNRT) and atrioventricular reciprocating tachycardia (AVRT) are two similar supraventricular re-entry tachycardias (SVT) emerging in relatively young age in patients without apparent structural heart disease or significant comorbidities. The treatment of choice in those patients is radiofrequency ablation (RFA).
The PPRA study is a prospective observational study developed to thoroughly analyze quality of life, utility and willingness-to-pay of Polish patients undergoing RF ablation of AVNRT or AVRT.
Based on collected data the investigators will prepare a profile of patient who will benefit most from radiofrequency ablation and who should be scheduled in first place for the ablation in case of problems with accessibility to this service.
What is more an analysis of medical and indirect costs of care will be performed.

- Health-related quality of life (HRQOL) [ Time Frame: two months ] [ Designated as safety issue: No ]Mean score of Patient Perception of Arrhythmia Questionnaire (PPAQ) - a disease-specific QoL questionnaire for patients suffering from supraventricular tachycardia translated and validated according to ISPOR (International Society For Pharmacoeconomics and Outcomes Research) guidelines
- Utility of health state [ Time Frame: two months ] [ Designated as safety issue: No ]Mean score of EQ-5D - a generic questionnaire measuring a health state utility (official Polish translation)
- Medical and indirect cost [ Time Frame: one year ] [ Designated as safety issue: No ]Cross-sectional data gathered using original questionnaire designed to measure medical and indiresct costs related to arrhythmia incurred during a year preceding RFA
- Willingness-to-pay [ Time Frame: one day ] [ Designated as safety issue: No ]a cross-sectional willingness-to-pay questionnaire studying hypothetical situation where RFA was not financed by Polish Health Fund
- Effectiveness [ Time Frame: two days ] [ Designated as safety issue: Yes ]Data on medical history, final diagnosis, outcome of treatment, safety and future recommendations
