In recent papers QCD corrections to the decay [ital t][r arrow][ital H][sup +][ital b] were calculated by two groups with results that disagreed. Using dimensional regularization for both infrared and ultraviolet divergences, we confirm that the QCD corrections to the decay width [Gamma]([ital t][r arrow][ital H][sup +][ital b]) are equal to [Gamma]([ital t][r arrow][ital W][sup +][ital b]) in the limit of a large [ital t]-quark mass.
