Response to exercise in congenital complete atrioventricular block.
In 8 patients aged 8 to 17 years with congenital complete atrioventricular (AV) block, exercise testing was performed on a treadmill. Cardiorespiratory endurance performance was assessed by determination of the ventilatory threshold. The mean value for ventilatory threshold was significantly lower (p less than 0.005) than the normal mean value and averaged 76 +/- 16%, 75 +/- 17% and 75 +/- 16% ...

T HE CLINICAL and hemodynamic findings in patients with complete heart block have been reported by many authors.1-14 There is general agreement that irrespective of the etiology of the block, cardiac enlargement and increased stroke volume are the compensatory mechanisms for the slow rate. In a few studies ventricular rate and other hemodynamic changes have been followed during exercise.1-3' 13...
متن کاملSinus node function in children with congenital complete atrioventricular block.
AIMS Children with congenital complete atrioventricular block (CCAVB) often need pacemaker therapy. In these children, it may be preferable to use single-lead VDD pacing, but for VDD pacing a normal sinus node function is required. Our aim was to study sinus node function in children with CCAVB. METHODS AND RESULTS We longitudinally evaluated sinus rate in 36 children with CCAVB and normal an...
متن کاملCongenital complete atrioventricular block. A pace in time saves lives (?).
The study by Balmer et al. in the present issue of Europace lends support to our clinical notion that early intervention is beneficial even to the young individual. The children in this study that received a pacemaker had signs and/or symptoms such as bradycardia, exercise intolerance, syncope or heart failure that were ameliorated by pacemaker implantation. Three patients received a pacemaker ...
متن کامل1:1 atrioventricular conduction in congenital complete heart block.
A female neonate with congenital complete heart block developed atrioventricular conduction through an accessory pathway. Despite sinus rhythm and an adequate heart rate she developed severe dilated cardiomyopathy and died at age 14 months. This case illustrates that underlying heart block can be present in individuals with asymptomatic Wolff-Parkinson-White syndrome and that the dilated cardio...
