Abstract:
In patients with congenital heart disease presenting with bradyarrhythmia, many electrophysiological abnormalities are found. This report presents a case of a man with surgically corrected single atrium and pulmonary valve stenosis, atrial standstill, delayed AV node conduction, first-degree intra- and second-degree infra-His block, who was permanently paced from a restricted excitable area of the low right atrium, as the pacing threshold was unacceptable at any ventricular site.
