In this paper, we revise Monti's results on the blow-ups of H-perimeter minimizing sets in ℍn. Monti demonstrated that the Lipschitz approximation of the blow-up, after rescaling by the square root of the excess, converges to a limit function for n ≥ 2. However, the partial differential equation he derived for this limit function φ through contact variation is incorrect. Instead, the correct equation is that the horizontal Laplacian of the limit function φ is independent of the coordinate y1 and solves equation 1 weakly.
