The invention relates to a device for epicardial support and/or resumption of cardiac activity. Said device comprises a double membrane (1) consisting of an elastic internal membrane (2), a non-expandable outer membrane (3), and a closed cavity (4) which is formed thereinbetween and can be inflated and deflated by means of a fluid. The aim of the invention is to improve one such device such that, in the critical post-operative phase, the heart can be stimulated in a simple manner. To this end, at least one probe/electrode unit (7, 8) for the epicardial derivation of the ECG and/or the signal transmission and conversion of an external pacemaker is arranged on the inner side (6) of the inner membrane (2) facing the heart (5).
