Coronavirus disease 2019 (COVID-19) is a pandemic caused by the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The spread of the virus was rapid and currently COVID-19 cases are present worldwide in 213 countries, area or territories. Researchers worldwide are working and sharing their contribution regarding epidemiology, prevention, treatment, clinical and diagnostic patterns of the COVID-19. Current review is another contribution to the current knowledge, presenting the data in organized and systematic format about the current pandemic of COVID-19. The epidemiological information presented in the paper is subject to change as new cases are diagnosed and status of active cases is updated on daily basis.

La enfermedad por coronavirus de 2019 (COVID-19) es una pandemia causada por un nuevo coronavirus, el coronavirus causante del síndrome respiratorio agudo severo 2 (SARS-CoV-2). La difusión del virus fue rápida y, actualmente, existen casos de COVID-19 a nivel mundial en 213 países, áreas o territorios. Los investigadores internacionales trabajan y comparten sus contribuciones en cuanto a epidemiología, prevención, tratamiento, patrones clínicos y diagnósticos de COVID-19. La presente revisión es otra contribución al conocimiento actual, que presenta los datos sobre la pandemia de COVID-19 en formato organizado y sistemático. La información epidemiológica presentada en el documento está sujeta a cambios, a medida que se diagnostiquen nuevos datos y se actualice el estatus de los casos activos, de manera diaria.

Coronavirus disease of 2019 (COVID-19) is a cause of significant morbidity and mortality worldwide. Although COVID-19 clinical manifestations are mainly respiratory, major cardiac complications are being reported. The mechanism of cardiac injury and arrhythmias is unclear. Also, drugs currently used to treat the COVID-19 may prolong the QT interval and may have a proarrhythmic propensity. The study aims to investigate the effects of COVID-19 infection with asymptomatic and mild symptoms on trans-myocardial repolarization parameters in children without treatment. A total of 105 COVID-19 patients were compared with 40 healthy children. The patient and control group data were compared by calculating the QT interval, corrected QT (QTc), QT dispersion (QTd), QTc dispersion (QTcd), Tp-e, Tp-e dispersion, Tp-e/QT ratio, and Tp-e/QTc ratio on the 12-lead surface electrocardiogram. The mean age was determined as 11.2 ± 0.3 years in the patient group, and 10.8 ± 2.1 years in the control group. In the COVID-19 group, QTd, QTcd, Tp-e, Tp-e dispersion, Tp-e/QT ratio and Tp-e/QTc ratio were statistically higher than the control group. The ventricular repolarization was impaired even in asymptomatic children with COVID-19 infection. These results suggest the need to further assess the long terms risks of prolonged QT dispersion in the setting of COVID-19 infection.
