BACKGROUND Chronic right ventricular (RV) pacing has been associated with decreased exercise capacity and left ventricular (LV) function in adults with congenital complete atrioventricular block (CCAVB), but not in children. OBJECTIVE The purpose of this study was to evaluate the exercise capacity and LV function in pediatric patients with CCAVB receiving chronic RV pacing. METHODS We prospectively evaluated pediatric patients with isolated CCAVB receiving atrial synchronous RV pacing for… CONTINUE READING
