An infant with a history of l-transposition of the great vessels, ebsteinoid tricuspid (systemic) valve, ventricular septal defect, atrial septal defect and patent ductus arteriosus was admitted at birth.Patient was status post placement of pulmonary artery band, ligation of pda, ventricular septal defect enlargement, patch closure of the tricuspid valve, atrial septectomy and tracheostomy.The patient had complete heart block, and so was pacemaker dependent.The pacemaker was due for a battery change.In preparation for the procedure, a second pacemaker was at the bedside and set for the patient's parameters.The back-up pacemaker's batteries were changed first.During the primary pacemaker's battery change, once the battery was placed in the pacemaker, the pacemaker's screen went blank and the patient's monitor showed asystolic heart rhythm.The patient's arterial waveform went flat.The staff quickly changed to the back-up pacemaker and so the patient did not suffer any ill-effects.The pacemaker was sent to biomed for evaluation.
