  We evaluate the feasibility of measuring the $Z$ polarization from a heavy
Higgs signal in the decay channel $H\rightarrow ZZ \rightarrow \ell^+
\ell^-\nu\bar{\nu}$. Including gluon fusion production of the Higgs, continuum
production of $Z$ pairs and the QCD background of single $Z$ production with a
missing jet, we find that the average value of a new variable to measure the
$Z$ polarization, as a function of transverse mass, will demonstrate the
existence of a Higgs boson for heavy Higgs masses up to 800 GeV at the LHC with
an integrated luminosity of 10$^5$ pb$^{-1}$.
