An epicardial stimulation lead includes a lead body having a connector at a proximal end for coupling the lead to a generator of an active implantable medical device. The lead also includes a distributor housing at a distal end of the lead body and means for anchoring the distal end of the lead body to the epicardium. The lead also includes an active part having a plurality of microcable conductors, the proximal ends being coupled to the distributor housing, the distal ends being free. Each microcable has a diameter of at most equal to 2 French. Each microcable includes at least one denuded area in the insulating coating forming a stimulation electrode adapted to contact or penetrate an epicardium wall. Each microcable also includes a transverse elongated member extending at an angle relative to the main direction of the microcable for penetrating into the epicardial wall.
