Abstract
Several cardiovascular diseases and arrhythmic disorders have been described in COVID-19 era as likely related to SARS-CoV-2 infection. The prognostic relevance of bradyarrhythmias during the infection has not been yet described and no data are available about long-term heart conduction disorders. A review of literature concerning the association between hypokinetic arrhythmias and COVID-19 from January 2020 to February 2021 was performed. The key-words used for the research were: "sinus node disfunction," "sick sinus syndrome (SSS)," "sino-atrial block," "atrio-ventricular block (AVB)," "bradyarrhythmias," and "COVID-19″ or "SARS-CoV-2.″ Excluding "relative bradycardia," a total of 38 cases of bradyarrhythmia related to SARS-CoV-2 infection have been described, even in very young people, requiring in many cases a definitive pacemaker implantation. Furthermore, we report a case of non-hospitalized 47-years old man with a SSS developed as a consequence of mild SARS-CoV-2 infection. While in all described cases heart conduction disorders were found at presentation of the infection or during hospitalization for COVID-19, in our case the diagnosis of SSS was made after the resolution of the infection. Although rarely, heart conduction disorders may occur during COVID-19 and the present case highlights that a cardiological follow up may be desirable even after the resolution of infection, especially in the presence of symptoms suggesting a possible heart involvement.
