The $^{51}\mathrm{V}$ nuclear spin-lattice relaxation rate $1∕{T}_{1}$ has been measured to study the dynamical magnetic properties of the quasi-one-dimensional conductor $\ensuremath{\beta}\text{\ensuremath{-}}{\mathrm{Na}}_{0.33}{\mathrm{V}}_{2}{\mathrm{O}}_{5}$. We find that the sodium ordering below ${T}_{\mathrm{Na}}\ensuremath{\sim}242\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ leads to drastic changes in $1∕{T}_{1}$ at the $\mathrm{V}2$ and $\mathrm{V}3$ sites, which may be ascribed to the change from the random to the regular potentials and the reconstruction of the local band due to the $2b$ lattice modulation. The wave vector $\mathbf{q}$ and temperature $T$ dependences of the dynamical susceptibilities are discussed from the analysis of both $1∕{T}_{1}T$ and the Knight shifts in the metallic phases. A jump of $1∕{T}_{1}$ due to the metal-insulator transition is observed at ${T}_{\mathrm{MI}}\ensuremath{\sim}135\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ and an activated-like reduction of $1∕{T}_{1}$ maybe owing to the development of the charge disproportionation is seen with decreasing $T$ below ${T}_{\mathrm{MI}}$.
