A simple formalism, based on the Goldstone-boson equivalence theorem, is described for calculating O(g2mH2/mW2) radiative corrections in the standard model. We apply this method to heavy-Higgs-boson decays and find that the dominant decay rates (W+W-) and (ZZ) are enhanced by a factor 1+(g2/82)(mH2/mW2) (19/16-3)/83 +(5/482). The same enhancement applies to heavy-Higgs-boson production from W+W- and ZZ fusion. Corrections of O(g2lnmH) are also briefly discussed.
