Let (K, v) be a Henselian field with a residue field \widehat K and value group v(K), and let ℙ be the set of prime numbers. This paper finds conditions on K, v(K) and \widehat K under which every algebraic associative central division K-algebra R contains a central K-subalgebra \widetilde R decomposable into a tensor product of central K-subalgebras R p, p ∈ ℙ, of finite p-primary dimensions [R p\colon K], such that each finite-dimensional K-subalgebra Δ of R is isomorphic to a K-subalgebra \widetilde Δ of \widetilde R.
