| Summary: | After undergoing surgery for a perimembranous ventricular septal defect and discrete membrane resection, a 7-year-old patient developed complete atrioventricular block and received an epicardial pacemaker. When the epicardial pacemaker reached end-of-life status, a transvenous pacemaker was implanted. Due to the low basal rate setting of this newly implanted transvenous pacemaker, the patient experienced bradycardia-induced acquired long-QT syndrome (LQTS), subsequently resulting in episodes of ventricular fibrillation. This case report discusses the mechanisms leading to acquired LQTS and fibrillation, and emphasizes the importance of an appropriate basal pacing rate, especially in pediatric patients, to avoid life-threatening arrhythmias. |
