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.
