R-wave synchronised atrial pacing in post-operative junctional ectopic tachycardia using a transoesophageal pacemaker

Abstract

AbstractWe report the first case of R-wave synchronised atrial pacing using a transoesophageal pacemaker. A 3-month-old baby developed a junctional ectopic tachycardia after surgical closure of a ventricular septal defect. R-wave synchronised atrial pacing with an external pacemaker was not possible owing to dislocation of the atrial epimyocardial pacing wires. Therefore, a temporary oesophageal pacemaker was connected in series to the external pacemaker to allow transoesophageal atrial pacing triggered by the preceding ventricular actions.
