FAMILIAL AGGREGATION OF ATRIOVENTRICULAR CONDUCTION DISTURBANCES IN THE KRASNOYARSK FAMILIES
Accumulation of cases of atrioventricular blocks in the Krasnoyarsk families for a ten-year period (2001–2011) was analyzed. Familial aggregation of atrioventricular blocks between proband’s relatives and between men and women separately was assessed. Statistical criteria χ2 and Fisher’s test used in statistical analysis.There was an increased number of cases of atrioventricular blocks among proband’srelatives, mainly of I degree of kinship. We founded the incidence of the disease among proband’s relatives significantly exceeds the population frequency of this nosology. Atrioventricular conduction disturbance prevalents among the women aged up to 19 years. Penetrance of atrioventricular blocks in Krasnoyarsk families was calculated by sibs method of Weinberg segregation analysis. Penetrance of atrioventricular blocks in Krasnoyarsk families is 69,56 %.
