We provide a characterization of intrinsic Lipschitz graphs in the sub-Riemannian Heisenberg groups in terms of their distributional gradients. Moreover, we prove the equivalence of different notions of continuous weak solutions to the equation ∂φ ∂z+∂ ∂t[φ 2 /2]=w, where w is a bounded measurable function.
