The in-medium sum rules are employed to calculate the shifts in the mass and residue as well as the scalar and vector self-energies of the heavy ΛQ,ΣQ and ΞQ baryons, with Q being b or c quark. The maximum shift in mass due to nuclear matter belongs to the Σc baryon and it is found to be ΔmΣc=936MeV. In the case of residue, it is obtained that the residue of Σb baryon is maximally affected by the nuclear medium with the shift ΔλΣb=0.014GeV3. The scalar and vector self-energies are found to be ΣΛbS=653MeV, ΣΣbS=614MeV, ΣΞbS=17MeV, ΣΛcS=272MeV, ΣΣcS=936MeV, ΣΞcS=5MeV and ΣΛbν=436±148MeV, ΣΣbν=382±129MeV, ΣΞbν=15±5MeV, ΣΛcν=151±45MeV, ΣΣcν=486±144MeV and ΣΞcν=1.391±0.529MeV.
