Key result
Among 108 children with isolated complete atrioventricular block, 81.4% required pacemaker implantation during follow-up, most commonly due to significant bradycardia.
Why the study?
Isolated complete atrioventricular block is a rare disease often linked to maternal autoantibodies, and midterm clinical and follow-up data from diagnosed patients needed evaluation.
Observational (n=108)
No
Isolated complete AV block in children frequently requires pacemaker implantation (81.4%), necessitating careful follow-up for pacing-induced left ventricular dysfunction, which may be treated with cardiac resynchronization therapy.
No takes yet. Share an insight, caveat, or question.
Supports vigilant surveillance for bradycardia in pediatric isolated complete AV block; leaves open optimal pacing timing and LV function outcomes.
Ayşe Sülü (2023) conducted an observational in Isolated complete atrioventricular block (n=108). Isolated complete atrioventricular block was evaluated on Pacemaker implantation. Among 108 children with isolated complete atrioventricular block, 81.4% required pacemaker implantation during follow-up, most commonly due to significant bradycardia.
