Three-loop electroweak corrections to the rho-parameter, sin^2 theta_eff   and the W-boson mass in the large Higgs mass limit
  A review of the calculation of the leading three-loop electroweak corrections to the rho-parameter, sin^2 theta_eff and the W-boson mass is presented. The heavy Higgs mass expansion and the renormalization are discussed.
