A revised and complete list of the electroweak chiral lagrangian operators up to dimension-four is provided. The connection of these operators to the S, T and U parameters and the parameters describing the triple gauge boson vertices WWγ and WWZ is made, and the size of these parameters from new heavy physics is estimated using a one flavor-doublet model of heavy fermions. The coefficients of the chiral lagrangian operators are also computed in this model.
