Abstract

Respiratory symptoms constitute one of the most significant manifestations of the coronavirus infection. SARS-CoV-2 (COVID-19) may lead to a life-threatening condition called “multisystem inflammatory syndrome in children (MIS-C),” which can affect many organs and systems, such as cardiovascular, respiratory, gastrointestinal, and renal systems. The condition might lead to severe and irreversible damage.
Myocarditis is one of the presentations of COVID-19 in children. Cardiac tissue inflammation could enhance the automaticity of cells and develop different arrhythmias.
Here, we report a pediatric case of MIS-C with cardiac involvement inducing atrial tachycardia and sinus node dysfunction. (Iranian Heart Journal 2024; 25(2): 96-101)
