Insights
Diphtheria can cause complete heart block in children. Aggressive management, including pacing, can lead to recovery in many cases of diphtheric myocarditis.
Area of Science:
- Pediatrics
- Cardiology
- Infectious Diseases
Background:
- Diphtheria remains a global health concern.
- Diphtheric myocarditis is a serious complication.
- Complete heart block is a rare but life-threatening consequence of diphtheric myocarditis.
Observation:
- This report details six pediatric cases of diphtheric myocarditis presenting with complete heart block.
- The study observed the outcomes of these young patients.
Findings:
- Three out of the six children survived.
- One patient experienced persistent complete heart block post-treatment.
- Aggressive supportive care, including transvenous pacing, was administered.
Implications:
- Early and intensive management strategies are crucial for improving survival rates in children with diphtheric myocarditis and complete heart block.
- Transvenous pacing can be a vital intervention for managing this severe cardiac complication.
- Further research into optimal treatment protocols for diphtheric myocarditis is warranted.
Abstract:
Diphtheria continues to be reported from many parts of the world. Complete heart block is rare but often fatal complication of diphtheric myocarditis. We report six children with diphtheric myocarditis who presented with complete heart block. Three patients survived, one with persistent complete heart block. Aggressive supportive management including transvenous pacing may result in complete recovery in a significant number of children with diphtheric myocarditis.
