IMPACT OF RADIOFREQUENCY CATHETER ABLATION ON HEALTH-RELATED QUALITY OF LIFE ASSESSED BY THE SF-36 QUESTIONNAIRE IN PATIENTS WITH PAROXYSMAL SUPRAVENTRICULAR TACHYCARDIA.

The aim of the study was to investigate the effect of catheter ablation on different aspects of health-related quality of life in association with patients' age, gender and the type of paroxysmal supraventricular tachycardia. We investigated 70 consecutive patients with paroxysmal supraventricular tachycardia (AV Nodal Reentrant Tachycardia (AVNRT), AV Reentrant Tachycardia (AVRT) or Atrial Tachycardia (AT)) who underwent a catheter ablation. The patients were asked to fill out the short form (SF-36) health questionnaire before the ablation on the day of the procedure and after 3 months of a successful catheter ablation and eight health concept scores (1. Physical functioning; 2. Role limitations due to physical health; 3. Role limitations due to emotional problems; 4. Energy/fatigue; 5. Emotional wellbeing; 6. Social functioning; 7. Bodily pain; and 8. General health) were assessed before and after ablation. All health concept scores improved significantly after successful catheter ablation procedure. The result for the whole group were as follows: 1. physical functioning improved from mean 61.42±24.82 to 77.15±18.80 (p<0.001). 2. Score for the role limitations due to physical health improved from 41.78±39.17 to 75.35±33.91 (p<0.001). 3. Score for the role limitations due to emotional problems improved from 48.07±42.32 to 80.46±33.81 (p<0.001). 4. Energy/Fatigue score improved from 56.71±19.97 to 68.78±16.40 (p<0.001). 5. Emotional wellbeing score improved from 58.22±17.31 to 71.88±14.33 (p<0.001). 6. Social functioning score improved from 68.39±24.51 to 81.00±19.12 (p<0.001). 7. Pain score improved from 59.82±28.65 to 80.57±20.58 (p<0.001) and 8. General health score improved from 48.42±15.26 to 62.57±15.43 (p<0.001). This study shows that catheter ablation which can effectively cure the patients from the paroxysmal supraventricular tachycardia significantly improves physical, emotional and social health scores by eliminating the arrhythmia episodes and associated symptoms and anxiety in patients with paroxysmal supraventricular tachycardia irrespective of patient demographics and the type of the SVT.
