Abstract: An active implantable medical device for the treatment of heartbeat rate disorders including the detection, analysis and treatment of ventricular pauses. The device includes circuits for delivering ventricular stimulation, circuits for detecting a normal spontaneous ventricular cardiac activity; a circuit for controlling ventricular stimulation that is suitable to control the application of a stimulation in the absence of normal spontaneous ventricular activity; and the continuous recording of the current cardiac information, such as detected cardiac activity and/or of parameters representative of those events. It also includes an algorithm for the controlled inhibition of the ventricular stimulation such that ventricular pauses of a duration greater than a predetermined value (X) are detected, wherein the predetermined value evolves over time in a progressive manner, and the ventricular pauses occur during the periods of controlled inhibition of the ventricular stimulation.

Abstract: An active medical device that is able to detect and treat ventiliatory activity disorders during sleep. This device measures the patient's respiratory activity, delivers a signal of the ventiliatory activity of the patient, analyzes the ventiliatory activity signal, and detects the occurrence of hypopneas. The analysis includes calculating at regular intervals a sliding average of the signal of ventiliatory activity, comparing the values of the successive sliding averages thus calculated, and detecting an occurrence of an hypopnea when, for two successive sliding averages, the difference between the averages crosses a predetermined threshold of comparison. When the device is one that also delivers cardiac stimulation pulses, it is advantageously envisaged to modify an operating parameter, in particular the stimulation rate based on the detected hypopnea, to treat the hypopnea.

Abstract: An active medical device have an improved diagnosis of a sleep apnea syndrome. This device measures the respiratory activity of the patient, determines a state of activity, this state being likely to take, according to satisfaction of predetermined criteria, a value representative of a state of sleep of the patient, and analyzes a detected signal corresponding to the respiratory activity to detect, when the aforementioned state is a state of sleep, the presence of respiratory pauses, and thereby to produce an indicating signal of sleep apnea in the event of the occurrence of a respiratory pause of duration longer than a first predetermined duration. The analysis also includes inhibiting the production of the aforesaid indicating signal, or a treatment to resolve an apnea, when the duration of the detected respiratory pause is longer than a second predetermined duration, typically of at least one minute.

Abstract: An active medical device having an improved discrimination between an awake phase of a patient and a sleep phase of a patient. This device measures a physiological parameter of a patient, delivers a physiological signal with a slow time response variation, in particular a signal of minute-ventilation (signal MV), and detects whether the patient is in a phase of awakening or sleep. An average (VE) of the signal MV is calculated over a given number of respiratory cycle and compared with a predetermined threshold (Threshold MV), such that a first state of awakening is determined when the average is higher than the threshold, and a first state of sleep is determined in the contrary case. The device also measures patient activity (signal G), using a signal having a short response time.

Abstract: An active medical device that is able to detect and treat ventiliatory activity disorders during sleep. This device measures the patient's respiratory activity, delivers a signal of the ventilatory activity of the patient, analyzes the ventilatory activity signal, and detects the occurrence of hypopneas. The analysis includes calculating at regular intervals a sliding average of the signal of ventilatory activity, comparing the values of the successive sliding averages thus calculated, and detecting an occurrence of an hypopnea when, for two successive sliding averages, the difference between the averages crosses a predetermined threshold of comparison.
