Introduction Chronic right ventricular (RV) pacing is associated with deterioration in cardiac function, increased mortality and heart failure hospitalisation.1 The UK PACE (United Kingdom Pacing and Cardiovascular Events) trial reported an overall annual incidence of clinical heart failure (HF) of approximately 3% in patients implanted with either a single-chamber or dual-chamber pacemaker over a three-year follow-up duration.2 A broader-paced QRS duration at baseline and the presence of coronary artery disease (CAD) are independently associated with new-onset HF in patients requiring permanent RV pacing for high-degree atrioventricular (AV)

Introduction Atrioventricular (AV) block is an uncommon complication of myocarditis, which is most often observed in combination with underlying conditions such as that caused by cardiac sarcoidosis (CS), giant cell myocarditis (GCM) and acute lymphocytic myocarditis. Myocarditis is a broad term that describes inflammation of the myocardium, which can range from mild and self-limiting to fulminant variants that require cardiac transplantation. Patients with proven GCM and CS may benefit from immunosuppression, and it is important to investigate for underlying infiltrative disease in cases of myocarditis and AV block as specific treatments ma
