Conclusion:
Overall, while pediatric admissions among children with ICDs have been increasing over time there has been a decline in admissions among those with primary arrhythmia diagnosis and an increase in those with heart failure. The overall in-hospital mortality rate is low (1.3%). In-hospital mortality is associated with a diagnosis of cardiomyopathy or congenital heart disease; and the underlying driver for in-hospital death may be heart failure.
