Abstract: The system includes an active medical device with means for delivering defibrillation shocks; means for continuous collection of the patient current cardiac activity parameters; and evaluator means with neuronal analysis comprising a neural network with at least two layers. This neural network comprises upstream three neural sub-networks receiving the respective parameters divided into separate sub-groups corresponding to classes of arrhythmogenic factors; and downstream an output neuron coupled to the three sub-networks and capable of outputting an index of risk of ventricular arrhythmia. The risk index is compared with a given threshold, to enable or disable at least one function of the device in case of crossing of the threshold.

Abstract: The instrument includes a connector block (24) suitable for receiving a removable memory card (12), a printed circuit (20), a case including an opening (16) for insertion of the memory card, and contacts (48) for reprogramming the microcontroller (22). The reprogramming contacts (48) are disposed on the printed circuit (20) at a distance from terminals (26) for making contact with the memory card, in the space that the connector block (24) occupies on the printed circuit, and they are available from the inside volume of the connector block. The instrument is essentially lacking in any opening dedicated to accessing the reprogramming contacts, with access to these contacts being possible via the opening in the case and the inside volume of the connector block by inserting an insert (52) into the instrument instead of and replacing a memory card.
