Extracorporeal Membrane Oxygenation (ECMO) Cannula Stimulation of the Carotid Sinus Causing Bradycardic Pauses in a Patient With COVID-19.

Veno-venous extracorporeal membrane oxygenation (VV-ECMO) cannulation is a potential cause of episodic bradycardia during an intensive care course because of the proximal cannula insertion site being in the vicinity of the carotid sinus. Herein, we report the case of episodic bradycardia throughout a multi-week intensive care stay of a VV-ECMO recipient due to a severe coronavirus disease 2019 (COVID-19) infection that did not emerge for the rest of the patient's hospitalization after decannulation.
