Active implantable medical device with holter recording functions
First Claim
1. An active implantable medical device with Holter recording functions, comprising:
- means for collecting data relating to the state of the patient carrying the device and/or operation of this device, and means for analyzing the collected data to produce in response general representative information;
means for continuous collection of at least one monitored signal representative of a physiological function of the patient;
a data memory means, where the aforementioned general representative information is memorized in a durable way; and
means for analyzing the monitored signal in real time to detect the occurrence of at least one particular event; and
means for processing the memory means, operative in response to the means for analyzing to organize the memory, on detection of the occurrence of at least a particular event, in;
a first zone for memorizing said general information;
a second zone for continuous memorizing of said monitored signal; and
means able, on detection of the occurrence of said particular event by the analyzing means, for starting the aforementioned continuous memorizing of the monitored signal in the second storage area for a first period of time.

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.
