We consider radiative corrections to the decay rate [Gamma]([ital H][r arrow][ital ZZ]) of the heavy [ital CP]-even Higgs boson of the minimal supersymmetric model to two [ital Z] bosons. We perform a one-loop Feynman diagram calculation in the on-mass-shell renormalization scheme, and include the third generation of quarks and squarks. The tree-level rate is suppressed by a mixing angle factor and decreases as 1/[ital M][sub [ital H]] for large [ital M][sub [ital H]]. The corrected rate overcomes this suppression and increases with [ital M][sub [ital H]] for [ital M][sub [ital H]] sufficiently large. The corrections can be very large and depend in detail on the top-squark masses and [ital A] term, as well as the supersymmetric Higgs-boson mass parameter [mu].
