The electroweak O(α) radiative corrections to the decay of the heavy CP-even MSSM Higgs boson to weak gauge bosons are presented. Due to the suppression of the tree-level H0WW/H0ZZ coupling, the electroweak contributions to the partial decay width are significant. Although the effective Born decay width can be rather small for certain MA0 values (especially for large tanβ), the corrected partial widths at different values of MA0 are of comparable size.
