Complete heart block presenting as seizures requires a pacemaker one year post-VSD repair in Down syndrome.
Case Report (n=1)
Children presenting with seizure-like episodes after surgical correction of congenital heart defects should be evaluated for delayed complete heart block.

Delayed complete heart block may present as seizures after VSD repair in Down syndrome; single case leaves open need for prospective surveillance studies.
A child with Down syndrome, who had undergone uneventful ventricular septal defect repair one year earlier with a normal heart rate during routine follow-up, presented with recurrent seizure-like episodes that did not respond to antiepileptics. She was subsequently found to have complete heart block with significant bradycardia requiring permanent pacemaker insertion. This late and unusual presentation of complete heart block after ventricular septal defect repair is discussed. Prudence must be applied in the evaluation of children who have undergone surgical correction of congenital heart defects and presented with recurrent seizure-like episodes.

Chaiyakulsil et al. (2019) conducted a case report in Complete heart block after ventricular septal defect repair (n=1). Ventricular septal defect repair was evaluated on Complete heart block requiring permanent pacemaker insertion. A child with Down syndrome developed complete heart block requiring a permanent pacemaker one year after an uneventful ventricular septal defect repair, initially presenting as seizure-like episodes.
