After spontaneously acquiring complete heart block, two children presented with torsade de pointes as a result of inappropriate prolongation of the QT interval. Although both remain well following pacemaker insertion, their cases illustrate the importance of QT interval assessment in patients with atrioventricular block, and demonstrate that syncopal episodes, and possibly sudden death, in children with acquired heart block can be due to bradycardia-induced ventricular tachyarrhythmias, rather than extreme bradycardia per se.
两名儿童在自发发生完全性心脏传导阻滞之后，因QT间期不适当延长而出现尖端扭转型室速。尽管两人在植入起搏器后情况良好，但他们的病例说明了对房室传导阻滞患者进行QT间期评估的重要性，并表明获得性心脏传导阻滞患儿的晕厥发作以及可能的猝死可能是由心动过缓诱发的室性心律失常所致，而非心动过缓本身。
