Abstract
An active implantable medical device with RF telemetry comprising subcutaneous ECG electrodes. The case (12) of the device comprises electrodes (20, 22, 24, 26) for collecting subcutaneous ECG signals coming into contact with the patient'"'"'s tissues surrounding the case after implantation, as well as an RF telemetry antenna (30). These ECG electrodes are surface electrodes and the RF antenna is a surface antenna. The case (12) presents a significantly planar face (16) for mounting the ECG electrodes in an arrangement where these electrodes are significantly coplanar and spaced apart with each other, and receiving the surface RF antenna. A platelet (18) mounted onto the case comprises an insulating substrate comprising on its free face, conductive deposits (20, 22, 24, 26, 30) forming the ECG electrodes and the RF antenna.
