Key result
In children surviving fulminant myocarditis, all acute-phase arrhythmias resolved during the convalescent and remote phases, with no arrhythmias induced during electrophysiological assessment.
Population
7 consecutive pediatric patients with fulminant myocarditis hospitalized in an intensive care unit.

Case_series
Follow-up
up to remote phase (mean 2,190 days for signal-averaged ECG)

May support de-escalated long-term monitoring in survivors; hypothesis-generating and requires prospective validation.
Observational (n=7)
No
Life-threatening arrhythmias associated with pediatric fulminant myocarditis appear to be transient, resolving completely in survivors without long-term conduction abnormalities or inducible arrhythmias.
Ichikawa et al. (2011) conducted an observational in Fulminant myocarditis (n=7). Standard care including mechanical cardiopulmonary support (CPS) was evaluated on Electrocardiogram findings, arrhythmogenicity and abnormalities of the cardiac conduction system. In children surviving fulminant myocarditis, all acute-phase arrhythmias resolved during the convalescent and remote phases, with no arrhythmias induced during electrophysiological assessment.
