Temporary endoepicardial atrioventricular sequential pacing for complete heart block following complex surgery for congenital heart disease.

Complete heart block following intracardiac surgical repair for complex congenital heart disease is not uncommon. In the presence of ventricular dysfunction, ventricular pacing alone may not improve the cardiac output. We report the feasibility and efficacy of endoepicardial atrioventricular sequential pacing in a case of postoperative complete heart block.
