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. Brad-yarrhythmias 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 asympto-matic 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 ar-rest 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 sec-ond patient, 39 years old, presented bradyarrhythmia on the ninth day of infection, transient absence of P waves and junctional atrioventricular and idioventricular es-cape rhythms, as well as atrioventricular dissociation. No specific treatment was required.
