Abstract
The article presents a literary review of the effect of the new coronavirus infection (COVID-19) on the cardiovascular system, namely cardiac arrhythmias. Probable etiopathogenetic factors of arrhythmia formation in patients with COVID-19 infections are described. The analysis of clinical forms of rhythm disturbances in patients with COVID-19 is presented. It was found that the probability of developing arrhythmias is associated with the patient’s age, their stay in an intensive care unit, and the presence of comorbid pathology. The data of foreign authors who note such rhythm disturbances as atrial fibrillation and fluttering, ventricular tachycardia, and high degree intermittent atrioventricular blockade as the most common among patients with a new coronavirus infection are presented. There was an association between malignant arrhythmias, including ventricular tachycardia / ventricular fibrillation and an increase in troponin T levels compared to patients with normal troponin T levels. The problem of side effects of the drugs used in COVID-19 treatment, namely arrhythmias, is stated. The dependence is shown between concomitant diseases, low PaO2/FiO2 balance and occurrence of arrhythmias in the form of a new atrial fibrillation.
