We calculate the leading quark mass corrections of order $m_q\log(m_q)$,
$m_q$ and $m_q^{3/2}$ to the vector meson decay constants within Heavy Vector
Meson Chiral Perturbation Theory. We discuss the issue of electromagnetic gauge
invariance and the heavy mass expansion. Reasonably good fits to the observed
decay constants are obtained.
