Autonomic heart rate modulation in patients with coronavirus disease 2019 in mechanical ventilation.

Background: Patients with coronavirus disease 2019 on automatic mechanical ventilation have greater heart rate modulation with greater parasympathetic modulation.

Objective: To analyze the autonomic modulation of heart rate in critically ill patients with coronavirus disease 2019 on invasive mechanical ventilation.

Methods: A cross-section study was carried out with 36 individuals divided into two groups.
