Apparatus for telemetry equipment for communication with an active device implanted in the thoracic area of a patient This equipment includes a wave collector (16) essentially sensitive to a magnetic field so as to allow an exchange of signals through magnetic coupling (i.e., an inductive channel) with the implanted device (14). The wave collector is connected to an electronic circuit package (24) for transmission/reception and signal processing of acquired data and programming. The apparatus further comprises a cloth (10) in the form of a vest to be worn by and able to cover at least one part of the patient's anatomy, a support structure (18) for receiving and supporting the wave collector, and adjustable members able to fix the support structure at a chosen location of the cloth, for example, by means of hooking tapes (20) disposed on the support (18) and cooperating surface material on the cloth. Thus, after initial positioning of the wave collector in front of the area where the device is implanted, placement and maintaining of the wave collector will be fixed to that location each time the patient puts the cloth on.
