Abstract

BACKGROUND

There is limited data regarding the electrophysiological abnormalities and arrhythmias in children with COVID-19, including those associated with treatment using potentially proarrhythmic hydroxychloroquine (HCQ) and azithromycin (AZN).

OBJECTIVES

To describe the electrophysiologic findings and arrhythmias associated with pediatric COVID-19 and its treatment.

METHODS

A single-center retrospective chart review was undertaken and included all patients with (1) symptoms of COVID-19 and (2) PCR-positive nasopharyngeal swabs for SARS-CoV-2 who were placed on continuous telemetry for the duration of their hospitalization during March through May, 2020.

RESULTS

Thirty-six patients were included in the study. Significant arrhythmias were found in 6 (nonsustained ventricular tachycardia in 5 and sustained atrial tachycardia in 1). All were self-resolving and half prompted prophylactic antiarrhythmic therapy. Patients with significant arrhythmias were likely to have noncardiac comorbidities (4/6), but these were not more common than in patients without arrhythmias (20/30, P = 1). The use of HCQ was associated with statistically significant QTc prolongation (413 ± 19 ms vs 425 ± 16 ms, P =.005). QTc was not statistically different in patients with and without arrhythmias (425 ± 15 ms vs 425 ± 15 ms, P = 1).

CONCLUSIONS

In pediatric patients with PCR-positive active COVID-19 infection, significant arrhythmias are infrequent, but are more common than expected in a general pediatric population. Comorbidities are not more common in patients with arrhythmias than in patients without arrhythmias. COVID-19 treatment using HCQ is associated with QTc prolongation but was not associated with arrhythmias in pediatric patients.

The use of HCQ was associated with statistically significant QTc prolongation (413 ± 19 ms vs 425 ± 16 ms, P =.005). QTc was not statistically different in patients with and without arrhythmias (425 ± 15 ms vs 425 ± 15 ms, P = 1).</AbstractText>
<AbstractText Label="CONCLUSIONS">In pediatric patients with PCR-positive active COVID-19 infection, significant arrhythmias are infrequent, but are more common than expected in a general pediatric population. Comorbidities are not more common in patients with arrhythmias than in patients without arrhythmias. COVID-19 treatment using HCQ is associated with QTc prolongation but was not associated with arrhythmias in pediatric patients.</AbstractText>
