Single-center experience of temporary-permanent pacemaker use in COVID-19 patients supported with veno-venous ECMO: A case series.

Introduction: In the first year of the COVID-19 pandemic, nine out of 129 patients (7%) developed life-threatening bradycardia episodes ultimately requiring a TPPM, whilst being supported with VV-ECMO for severe COVID-19 ARDS in our tertiary cardio-pulmonary failure center.

Analysis: All subjects had asystole due to sinus node dysfunction and experienced at least one episode involving cardiopulmonary resuscitation. Most bradycardic events were seen in the context of vagal hypersensitivity.

Atrial pacing to suppress ventricular arrhythmias in the critically ill patients: a case report.

Background: Atrial and ventricular arrhythmias are common in the critically ill due to a variety of factors including sepsis, myocardial ischaemia, renal dysfunction, and electrolyte disturbances. Anti-arrhythmic medications can be useful to control arrhythmias but can result in bradycardia and haemodynamic compromise. A paced atrial rhythm alongside normal atrioventricular conduction can be helpful to treat bradycardia, prevent arrhythmias, and support cardiac output.

Thoracic surgery in patients on veno-venous extracorporeal membrane oxygenation for COVID-19 associated acute respiratory distress syndrome.

Objectives: The COVID-19 pandemic has generated a new type of acute respiratory distress syndrome (ARDS) arising as a complication of COVID-19 pneumonia. Extreme cases require the support of extracorporeal membrane oxygenation (ECMO). Here we present the outcomes of patients that underwent surgical tracheostomy or thoracic surgery at a single tertiary centre whilst on ECMO support for COVID-19 related ARDS.
