The purpose of this review is to systematize the literature on the effect of SARS-CoV-2 on the cardiovascular system, focusing on changes in the surface electrocardiogram depending on the clinical course of the disease, the characteristics of the treatment and outcomes, and the possible identification of electrocardiographic predictors of complications, as well as sudden cardiac death in patients with non-coronarogenic syndromes with new virus infection (COVID-19). © 2020, Silicea-Poligraf.
