abstract = {We present a compact analytic result for the two-loop leading heavy top contribution to the rho-parameter which is valid for arbitrary Higgs mass. Our results confirm a recent calculation by Barbieri et al. [Phys. Lett. B 288 (1992) 95; preprint CERN-TH.6713/92 (1992)]. We directly calculate the physical W and Z amplitudes and explicitly check the validity of the Ward identities on which the calculation of Barbieri et al. was based. This also checks that the use of an anticommuting gamma5 PreServes the Ward identities. A corresponding formula for the ZbbBAR-vertex is given as well.},
