RODRIGUEZ AGUIRRE, Yasmani; ROSABAL GARCIA, Yoandro  and  LICEA SANTOS, Yazmin Ailen. Macro-reentrant atrial tachycardia of the atrial flutter type in a 2-month-old patient infected with SARS-CoV-2. Rev Cubana Pediatr [online]. 2022, vol.94, suppl.1  Epub Dec 15, 2022. ISSN 1561-3119.


On March 11, 2020, the first cases of COVID-19 were confirmed in Cuba.


To examine a complication of SARS-CoV-2 infection uncommon in pediatric ages and its treatment.

Case presentation:

A 2-month-old infant from Guantánamo province was delivered by cesarean section at 41.5 weeks. Due to maternal conditions, the newborn remained with the mother in the hospital for 45 days. Then the newborn was discharged and after 15 days at home was evaluated due to fever of 38 ° C during three consecutive days. A very high heart rate and euthermic state were observed. The antigen test and reverse transcriptase polymerase chain reaction and PCR tests for SARS-CoV-2 were positive, so the newborn was admitted to the pediatric intensive care unit with diagnostic impression of supraventricular tachycardia that is finally defined as atrial flutter. The treatment applied controlled the cardiac arrhythmia and contributed to its subsequent favorable evolution.


The findings of the physical examination and the data in the anamnesis allow the diagnosis of the patient in its early stage. The pathophysiology of complications in children is in the local regulation of ACE2 receptor expression, increased catecholamine production and an increased incidence of toxicity by drugs that produce acute cardiac injury and arrhythmia, symptoms that may be associated with dysfunction of the respiratory system and hematological changes or not in pediatric age.

Keywords : arrhythmia; supraventricular tachycardia; macro-reentrant; COVID 19; SARS-CoV-2 virus.
