Arrhythmia and COVID-19 in children.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection caused worldwide health problems, and coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization in March 2020. Cardiovascular complications of COVID-19 are not uncommon; among them, arrhythmia is considered a significant risk factor for poor health outcomes in adults. However, data are scarce on the arrhythmia of pediatric patients with SARS-CoV-2 infection, possibly due to their mild symptoms and low incidence of cardiovascular involvement. Multisystem inflammatory syndrome in children reportedly features increased cardiovascular involvement, but arrhythmic complications remain unidentified. Thus, here we review the epidemiology, manifestations, and outcomes of pediatric arrhythmia associated with COVID-19.
