|Abstract:||Background: Although several studies have demonstrated the deleterious consequences of chronic right ventricular (RV) pacing on ventricular function and synchronicity, its effects on health-related quality of life (HRQL) and physical capacity remains uncertain. Objectives: To evaluate the effect of RV pacing on HRQL and physical capacity of children and young adults with congenital complete atrioventricular (AV) block. Methods: Fifty consecutive patients with permanent RV cardiac pacing due to congenital AV block and under clinical follow-up for more than one year were enrolled. Multidimensional HRQL was assessed with the Short Form-36 Health Survey (SF-36) and Child Health Questionnaire (CHQ-PF50). Physical capacity was tested by the 6-minute walk distance test (6MWD). The scores for each domain and the distance performed at the 6MWD test were compared with demographic and clinical characteristics of patients, using the Student’s t-test and Qui-squaretest. Results: Domains presenting lower scores were Vitality (63.0±20.6), Pain(66.5±25.1) and Mental Health (67.3±20.4) in the SF-36 questionnaire; General Health Perceptions (64.0±15.0) and Parental Impact-Emotional (69.0±30.0) in the CHQ-PF50. Female gender (P=0.026), DDD pacing mode (0.008) and normal left ventricular ejection fraction (0.002) were associated with higher quality of life scores. The average distance performed at the 6MWD test was 677,2 meters (454,5 to 852,8). The 6MWD showed significant association with age (P=0.004), normal ventricular function (P= 0.031) and the absence of cardiovascular drugs use (P= 0.018). Conclusions: The results of this analysis indicated that chronic RV pacing did not affect the HRQL and physical capacity of young patients. Female gender, DDD pacing, normal ventricular function and the absence of cardiovascular medications were associated with better HRQL scores and with better results at 6MWD test.|
