Long-term follow-up of epicardial pacing and left ventricular dysfunction in children with congenital heart block

ConclusionsOur study suggests that RV free wall pacing may be a significant risk factor for LV dysfunction. Pacemaker-induced LV dysfunction was improved via lead relocation to the RV apex or cardiac resynchronization therapy upgrade. Future studies with a bigger sample size and longer-term follow-up are required to confirm our results.
