Abstract
The aim of this study was to investigate the predictive value of the rs1805124 polymorphism of the SCN5A gene with regard to idiopathic cardiac conduction disorders.The AG genotype frequency was significantly higher in patients with an atrioventricular block (61,2%±6,0%) compared with healthy control subjects (34,8%±2,3%), p<0.0001. The AG genotype frequencies among patients with only idiopathic complete right bundle-branch block (CRBBB) (54,2%±5,5%) and those with both CLBBB and LAH (50%±5,1) were significantly higher than in the control group (34,8%±2,3%), p<0.005.The AG genotype of the H558R (rs1805124) polymorphism of the SCN5A gene is a genetic predictor of idiopathic disorders of atrioventricular and intraventricular conduction.
