The mass and decay constant of the heavy quarkonia $h_{Q}(1P)$ and$h_{Q}(2P)$ (Q = b, c) with quantum numbers $J^{PC} =1^{+-}$ are calculated inthe framework of the two-point QCD sum rule method by taking into account thevacuum condensates up to eight dimensions. We compare our results forparameters of the $h_{b}(1P)$ and $h_{c}(1P)$ quarkonia, and their firstradially excited states $h_{b}(2P)$ and $h_{c}(2P)$ with available experimentaldata as well as predictions of other theoretical studies existing in theliterature. The results of present work may shed light on experimental searchesfor the $h_{c}(2P)$ state.
