Cardiac involvement has been reported in patients with COVID-19, which may be reflected by electrocardiographic (ECG) changes. Two COVID-19 cases in our report exhibited different ECG manifestations as the disease caused deterioration. The first case presented temporary SIQIIITIII morphology followed by reversible nearly complete atrioventricular block, and the second demonstrated ST-segment elevation accompanied by multifocal ventricular tachycardia. The underlying mechanisms of these ECG abnormalities in the severe stage of COVID-19 may be attributed to hypoxia and inflammatory damage incurred by the virus.
Des cas d’atteinte cardiaque se manifestant par des changements décelables à l’électrocardiogramme (ECG) ont été rapportés chez certains patients atteints de la COVID-19. Nous exposons les cas de deux patients atteints de la COVID-19 dont les ECG révèlent une détérioration de la fonction cardiaque causée par la maladie. Dans le premier cas, le patient a présenté temporairement un aspect SIQIIITIII suivi d’un bloc auriculo-ventriculaire quasi complet réversible, tandis que dans le deuxième cas, le patient a présenté une élévation du segment ST accompagnée d’une tachycardie ventriculaire multifocale. Ces anomalies électroencéphalographiques chez des patients gravement atteints de la COVID-19 pourraient s’expliquer par l’hypoxie et les lésions inflammatoires provoquées par le virus.
