EDITORIAL Is the left ventricle the preferred pacing site in all children with atrioventricular block?

This editorial refers to ‘Preserved cardiac synchrony and function with single-site left ventricular epicardial pacing during mid-term follow-up in paediatric patients’ by M. Tomaske et al., on page 1168 Cardiac pacing for the treatment of bradycardia has been applied in children of all age groups for many years. In the paediatric popu-lation, the most common indications for cardiac pacing are auto-immune-mediated congenital atrioventricular block (CAVB) and acquired CAVB after congenital heart surgery. Traditionally, the right ventricular (RV) apex has been used for transvenous ven-tricular pacing leads because it is easily accessible and allows a stable position and low pacing thresholds. In young children, many centres prefer to place epicardial ventricular pacing leads, which are usually attached to either the RV apex or the RV free wall. Although thousands of children have profited from pacin
