We study the scheme dependence of the two-loop expression for the [rho] parameter of the standard model in the heavy [ital t]-quark mass limit [ital m][sub [ital t]][much gt][ital m][sub [ital W]]. In the MS scheme the two-loop electroweak correction to the [ital O]([ital m][sup 2][sub [ital t]]) term in [Delta][rho] is found to be greater than the QCD [alpha][sub [ital s]] correction.
