Atrioventricular conduction time--a heritable trait?
The atrioventricular conduction time was studied in 35 adult relatives of six and nine probands with short and long P-R intervals, respectively. A significant difference between the distributions was found. The distribution patterns were compatible with the presence of major genes.
