We present a general analysis of shot noise in an electronic Mach-Zehnder interferometer, of the type investigated experimentally [Yang Ji et al., Nature 422, 415 (2003)], under the influence of dephasing produced by fluctuations of a classical field. We show how the usual partition noise expression T(1-T) is modified by dephasing, depending on the power spectrum of the environmental fluctuations.
