An infant experienced temporary complete heart block after valve surgery. Postoperative electrocardiograms (ECGs) revealed a right bundle branch block, clarifying a complex heart rhythm during recovery.

Area of Science:

  • Pediatric Cardiology
  • Cardiac Surgery
  • Electrophysiology

Background:

  • Congenital heart defects often require surgical intervention.
  • Aortic and mitral valve surgery in infants can carry significant risks.
  • Postoperative arrhythmias are a known complication in pediatric cardiac surgery.

Observation:

  • An infant developed transient complete heart block post-aortic and mitral valve surgery.
  • The infant later presented with a variable morphology wide complex rhythm.
  • Intermittent narrow complex beats were also observed during recovery.

Findings:

  • Initial postoperative electrocardiogram (ECG) showed a right bundle branch block.
  • The presence of right bundle branch block aided in understanding the complex rhythm.

  • This suggests a relationship between the surgical intervention and the observed electrophysiological changes.

    • Implications:

    • Understanding postoperative ECG findings is crucial for managing complex arrhythmias in infants.
    • Early identification of conduction abnormalities can guide clinical management.
    • This case highlights the importance of detailed ECG analysis in the postoperative period for pediatric cardiac surgery patients.
