Introduction As the number of cases of coronavirus disease 2019 (COVID-19) has reached tens of millions worldwide, the understanding of its clinical manifestations has grown. These have been described as a range of systemic repercussions resulting from an interplay between direct organ damage and exaggerated host immune response. , In a descriptive case series study of COVID-19 patients in Wuhan, 44% of patients had either elevated cardiac biomarkers or new changes in electrocardiogram (ECG) and imaging exams, and 34% of […]

Abstract Cardiovascular manifestations of COVID-19 include cardiac rhythm disturbances, whose mechanisms, incidence, and most common types are not well established in this population. Intense inflammatory response and metabolic activity contribute to recurrence of pre-existing arrhythmias, and other arrhythmias can occur due to myocardial injury, acute coronary insufficiency, and electrolyte disturbances. Brady- and tachyarrhythmias, as well as conduction disorders have been described. QT interval prolongation and fatal ventricular arrhythmias ( Torsades de Pointes ) may result from the pathological process or […]
