Abstract

This device collects and analyzes general data on the state of the patient, and collects continuously a monitored signal representative of a physiological function. It includes a memory with a first zone for the durable memorizing of these data, and analyzes in real time the monitored signal to detect there the occurrence of a particular event. The memory includes a second zone for the continuous memorizing of the monitored signal over a first period of time, the memorizing being started on detection of a particular event. The device can also collect context information representative of circumstances possibly related to the occurrence of the particular event. The memory then includes a third zone, for the conditional memorizing of this information on detection of an event, for a second period of time shorter than the first period. The monitored signal can, for example, be a ventilatory signal, in which case the event is a hypopnea and/or a apnea, the context information include a ventricular and/or atrial electrogram, events markers of the heartbeat rate and/or a signal of the peak endocardial acceleration. The monitored signal can be also an electrogram signal, a signal of the peak endocardial acceleration, a series of events markers of the heartbeat rate and/or an intracardiac signal of bio-impedance. The event is then a preset disorder of the heartbeat rate and/or a disorder of atrio-ventricular conduction, the context information include the events markers of the heartbeat rate, a signal of the peak endocardial acceleration and/or a ventilatory signal.
