Abstract A patient with coronavirus disease 2019 showed complete atrioventricular block on electrocardiogram. The patient was undergoing mechanical ventilator treatment for severe hypoxia. Intrathoracic pressure was reduced by adjusting the tidal volume and the positive end-expiratory pressure of the mechanical ventilator. After that, complete atrioventricular block didn’t occur during the hospitalization.
