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 a state of a patient carrying the device and/or operation of the device;
means for analyzing the collected data relating to the state of the patient to produce general representative information;
means for continuous collection of a monitored signal representative of a physiological function of the patient;
a data memory means internal to the device;
means for analyzing the monitored signal in real time to detect an occurrence of a particular physiological event of the patient; and
means for programming the data memory means,wherein the means for programming is configured to commutate the data memory means between a standard mode and a dedicated mode on detection of the occurrence of the particular physiological event, andwherein, in the standard mode, the means for programming also is configured to record the general representative information in a first zone of the data memory means, and in the dedicated mode, the means for programming is configured to dynamically allocate a second zone in the data memory means and record the monitored signal representative of said physiological function in the second zone for a first period of time while continuing to store the general representative information in the first zone.

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.
