In this contribution of 8 pages to the proceedings of the Les Houches session on “Quantum fluctuations” held in 1995 we briefly review the following aspects of dissipative quantum systems: damped harmonic oscillator, dissipation in quantum mechanics, path integrals and effective action, decay of a metastable state.
