Abstract
Arrhythmias in COVID-19 patients are associated with hypoxia, myocardial ischemia, cytokines, inflammation, electrolyte abnormalities, pro-arrhythmic or QT-prolonging medications, and underlying heart conditions such as severe congestive heart failure, inherited arrhythmia syndromes, or congenital heart conditions. In the pediatric population, multisystem inflammatory syndrome can lead to cardiac injury and arrhythmias. In addition, arrhythmias and cardiac arrests are most prevalent in the critically ill intensive care unit COVID-19 patient population. This review presents an overview of the association between COVID-19 and arrhythmias by detailing possible pathophysiological mechanisms, existing knowledge of pro-arrhythmic factors, and results from studies in adult and pediatric COVID-19 populations, and the clinical implications.
