Effect of catheter ablation of the XXXX on quality of life and exercise tolerance in @entity955 .

@entity713 @entity1 @entity955
The effect of catheter ablation of the @entity713 ( @entity713 ) and implantation of a rate-adaptive pacemaker on quality of life and exercise capacity was evaluated prospectively in 12 consecutive @entity1 with @entity955 ( @entity955 ). All @entity1 had been demonstrated to have paroxysmal @entity955 that was refractory to medical therapy over a long period of time (mean 9 +/- 7 years). @entity1 performed a symptom-limited treadmill exercise test on the day before catheter ablation and 6 weeks after hospital discharge. Quality of life was measured using the physical dimension of the McMaster Health Index Questionnaire and the Psychological General Well-Being Index before and 6 weeks after ablation. There were no serious complications related to catheter ablation or permanent pacemaker implantation. All @entity1 remain in complete @entity713 with a completely paced rhythm at a mean follow-up of 8 +/- 2 months. The McMaster Health Index scores increased from a mean of 0.69 +/- 0.20 before to 0.92 +/- 0.14 after ablation (p = 0.002). The mean Psychological General Well-Being score improved from 59.8 +/- 14.8 at baseline to 84.9 +/- 13.6 6 weeks after discharge (p = 0.001). Treadmill exercise duration increased from 6.4 +/- 4.6 to 9.9 +/- 2.6 minutes (p = 0.03) and correlated strongly with changes in functional capacity measured with the McMaster Health Index (r = 0.70, p = 0.03). These results suggest that catheter ablation of the @entity713 junction and implantation of a rate-adaptive pace-maker significantly improve the quality of life and exercise capacity of @entity1 with paroxysmal @entity955 refractory to medical therapy.
