Cardiac Arrhythmias in Pediatric Age: Are They Triggered by SARS-CoV-2 Infection?

Coronavirus disease 2019 is a highly contagious infectious disease. Research on heart rhythm disorders in children affected by COVID-19 infection is quite lacking. An infant and a congenital heart disease (CHD) teenager with a pacemaker presented fascicular tachycardia and atrial flutter, respectively, during COVID-19 pauci-symptomatic infection. The hemodynamic condition was always stable. The self-resolving trend of the atrial flutter and progressive resolution of the ventricular tachycardia occurred in conjunction with the negativization of the swab. These particular tachyarrhythmias have been reported as a form of potential arrhythmic complication during active pauci-symptomatic COVID-19 infection for the first time ever.
