  We consider the non-Hermitian, parity-time (PT) symmetric extensions of the
one-dimensional Su-Schrieffer-Heeger (SSH) model in the topological non-trivial
configuration. We study the properties of the topologically protected edge
states, and develop an effective two-state analytical description of the system
that accurately predicts the PT-symmetry breaking point for the edge states. We
verify our analytical results by exact numerical calculations.
