Background
Corona virus disease 2019 (COVID-19) contributes to cardiovascular complications including arrhythmias due to high inflammatory surge. Nevertheless, the common types of arrhythmia amongst severe COVID-19 is not well described. New onset atrial fibrillation (NOAF) is frequently seen in critically ill patients and therefore we aim to assess the incidence of NOAF in severe COVID -19 and its association with prognosis.
