May suggest a rare substrate in young sudden death; hypothesis-generating and requires validation before any clinical or screening implications.
Case Report (n=2)
Persistent fetal dispersion of the A-V node and His bundle may provide an anatomical substrate for lethal arrhythmias and sudden unexpected death in young individuals.
James et al. (1976) conducted a case report in Sudden unexpected death (n=2). Persistent fetal dispersion of the atrioventricular node and His bundle was evaluated on Histological appearance of the A-V node and His bundle. Persistent fetal dispersion of the A-V node and His bundle was found in 2 victims of sudden unexpected death, suggesting a potential anatomical substrate for lethal electrophysiological disturbances.
