An increased slowing of cardiac conduction induced by sodium channel blockers is remarkably observed in carriers of an Asian-specific promoter haplotype [haplotype B (HapB)] of the cardiac sodium channel gene (SCN5A). We investigated the effect of HapB on the therapeutic range for serum flecainide concentration in Asian patients.
