ABSTRACT
Several cardiovascular diseases and arrhythmogenic events have been associated with COVID-19 due to SARS-COV-2 infection, a topic of current global interest. Bradyarrhythmias are less frequent than other types of arrhythmia. We present a patient at 27 weeks of pregnancy, who on the fourth day of infection presented asymptomatic transient sinus pauses that did not require treatment ( sinus bradycardia of 41 beats per minute, pauses of two seconds and junctional escape rhythm). She was diagnosed as possible atrial myopathy with third degree sinoatrial block, sinus arrest or atrial quiescence, primary sinoatrial node dysfunction due to myocarditis ( edema and inflammation of the conduction system). She continued under follow-up, since after the infection was overcome arrhythmical events may recur. The second patient, 39 years old, presented bradyarrhythmia on the ninth day of infection, transient absence of P waves and junctional atrioventricular and idioventricular escape rhythms, as well as atrioventricular dissociation. No specific treatment was required.
ABSTRACT
COVID-19 is a global health emergency. Cardiac arrhythmias are associated with cardiac damage and high mortality. There are at least three scenarios where they can occur: triggered by infection;in patients with a history of them;secondary to proarrhythmia due to antiviral drugs. This article aims to describe these scenarios and the treatment of cardiac arrhythmias in each one of them. © 2020, Cuban Society of Cardiology, Cuban Institute of Cardiology and Cardiovascular Surgery.
