Сardiac arrhythmias in people who have had a coronavirus infection COVID-19: A review

Heart rhythm disorders are one of the most common complications of coronavirus infection. Heart rhythm disorders can develop in 6-17% of hospitalized patients, and in convalescents, COVID-19 can manifest itself up to 12 months after the completion of the acute phase of the disease. Among the mechanisms for the development of cardiac arrhythmias, there are a direct cytopathic effect of SARS-CoV-2 on the myocardium, systemic inflammatory response syndrome, electrolyte imbalance, hypoxia, the use of antibacterial, antimalarial and antiviral drugs, exudative pericarditis, autonomic dysfunction. The main COVID-19-mediated heart rhythm disorders are sinus tachycardia and bradycardia, atrial fibrillation, ventricular tachycardia, long QT syndrome. Despite a significant amount of research, the literature data on the prevalence of certain types of cardiac arrhythmias (especially in COVID-19 convalescents), as well as methods for their correction, are somewhat contradictory and need to be clarified. Taking into account the impact of arrhythmia on the quality of life and mortality, active monitoring of convalescents of coronavirus infection, identification and development of approaches to the treatment of heart rhythm disorders in patients who have had COVID-19, seem to be relevant and promising areas in modern cardiology.
