System for monitoring at least one parameter representative of a decompensation of a cardiac failure by means of a subcutaneous implant

A system for monitoring at least one parameter representative of an episode of decompensation of a cardiac failure in a living being, the monitoring system comprising:

• a subcutaneous implant configured to be introduced under the skin of said living being, the subcutaneous implant comprising at least one electrocardiograph and one accelerometer configured to collect data relating at least to the functioning of the heart of the living being, and
• a computer server and a communication relay configured to allow at least the exchange of data collected by the subcutaneous implant with the computer server, the computer server being configured to calculate changes in at least one parameter, from among hemodynamic and/or respiratory and/or electrophysiological parameters, on the basis of the data collected by at least the accelerometer and the electrocardiograph,
• the subcutaneous implant comprising communication means configured to communicate data collected by at least the accelerometer and the electrocardiograph by means of a low-energy Bluetooth connection.
