For a heavy Higgs boson above the ttˉ threshold we consider three decay modes that could compete with decay to ttˉ, even in the alignment limit of a 2-Higgs doublet model. The decays H→AZ, Z′Z′ and τ′τ′ show that heavy Higgs decays can be an effective probe of new physics both within and beyond this model.
