The electroweak corrections at one-loop level to the process [ital H][r arrow][ital t[bar t]] are calculated, incorporating the top mass value announced recently by [ital CDF]. For [ital M][sub [ital H]][lt]1 TeV where a perturbative calculation is valid, the corrections themselves would gain a few to 20% increment in the decay width as the Higgs-boson mass [ital M][sub [ital H]] is increasing within the region, but they are in opposite direction to the [ital QCD] ones. If the electroweak and [ital QCD] corrections are considered together, the resultant decay width of the mode yields a reduction about a few percent of the tree level one.
