摘要： The present invention provides a method and apparatus for detecting and treating sleep respiratory events that includes a plurality of sensors gathering physiological data related to sleep respiratory events. A processor extracts an average cycle length and a frequency of at least one of Cheyne-Stokes respiration and periodic breathing based upon the physiological data, and determines whether therapy is required based on the average cycle length and the frequency.

摘要： An implantable medical device having a housing that encloses a pulse generator and a sensing module includes a housing-based cathode electrode electrically coupled to the pulse generator and to the sensing module. A sensing extension extending from the housing proximal end includes an anode electrode electrically coupled to the sensing module for sensing cardiac electrical signals. The sensing extension includes a flotation member that causes the sensing extension to extend away from the housing along a direction of flowing blood when the implantable medical device is deployed within a cardiovascular system of a patient.

摘要： A method and apparatus for discriminating between stable and unstable ventricular tachycardias based on a measurement of oxygen saturation. Reference values for average oxygen saturation level and of the pulsatile characteristic of the oxygen saturation level are taken while a patient is in a resting condition. Measurements of oxygen saturation are also taken in response to the detection of a high heart rate, and are compared to the reference measurements to discriminate between stable and unstable ventricular tachyarrhythmias. An unstable tachyarrhythmia is diagnosed if a tachycardia is diagnosed and the current oxygen saturation level is similar to the reference average oxygen saturation level or if the oxygen saturation as presently measured displays a decreased pulsatile characteristic as compared to the reference measurements. The discriminator is intended for use in conjunction with or as part of an automated cardioverter of the type capable of delivering differing therapies for termination of stable and unstable ventricular tachyarrhythmias, such as antitachycardia pacing, cardioversion and defibrillation.

摘要： An apparatus for determining a respiration parameter in a medical device in which a pressure sensor senses pressure signals, and a signal processor, coupled to the pressure sensor, receives the sensed pressure signals and generates corresponding sample points. A microprocessor continuously adjusts a breath detection threshold in response to the generated sample points to generate a current adjusted breath detection threshold, compares a current generated sample point to the current adjusted breath detection threshold, suspends the continuous adjusting of the breath detection threshold and sets the breath detection threshold equal to the most current adjusted breath detection threshold generated prior to the suspending, and determines the respiration parameter in response to a comparing of a next generated sample point to the set breath detection threshold.

摘要： The present invention relates to methods and apparatus for detection and treatment of syncope in an implantable medical device, and particularly to detection of syncope as a function of a predetermined increase in one or more respiration parameter and drop in heart rate and optionally delivering a pacing therapy in response thereto. The onset of a syncopal episode is declared when the patient's respiration rate and/or tidal volume and/or minute ventilation increases by a predetermined increment or threshold and a heart rate drops below a threshold heart rate drop. The threshold heart rate drop is preferably established as a function of the change in the respiration parameter.

摘要： The invention relates generally to a system and method for monitoring and automatically delivering a therapy for sleep-related disordered breathing. In one form the present invention relates to an external device for monitoring for sleep-related disordered breathing in communication with an implantable medical device for delivering an electrical stimulation therapy. In another form the present invention relates to an implantable medical device for detecting sleep-related disordered breathing episode(s) and an external apparatus (e.g., a CPAP machine) for providing therapy to terminate, and/or reduce, said episode(s). In this form of the invention, the implantable medical device communicates with the external apparatus so that the therapy provided corresponds in magnitude and duration to the severity and/or length of the episode(s). In yet another form, an implantable apparatus detects said disordered breathing episode(s) and a hybrid therapy is provided by both the implantable apparatus and an external apparatus.

摘要： An intracardiac ventricular pacemaker having a motion sensor is configured to produce a motion signal including an atrial systolic event and at least one ventricular diastolic event. The pacemaker is configured to set an atrial refractory period, detect a change in a ventricular diastolic event metric and adjust the atrial refractory period in response to detecting the change. The pacemaker sets set an atrioventricular pacing interval in response to detecting the atrial systolic event from the motion signal after expiration of the atrial refractory period.

摘要： A method and apparatus for cardiac pacing are provided in which pacing pulses are delivered at an increased rate (454, 470) in response to a detected intrinsic heart rate drop (505) and a special rate drop response detection scheme is temporarily disabled (510) until an intrinsic heart rate exceeds a predetermined threshold value (450). If the pacing rate reaches the lower pacing rate without sensing intrinsic activity, heart rate drop detection remains disabled and lower rate pacing continues. Rate drop detection is re-enabled (530) whenever sufficient sensed intrinsic activity indicates that a sudden intrinsic rate drop could occur again.

摘要： Procédé et appareil permettant de distinguer les tachycardies ventriculaires stables et instables, fondés sur une mesure de la saturation en oxygène. On prend des valeurs de référence du niveau moyen de saturation en oxygène et de la caractéristique pulsatile du niveau de saturation en oxygène lorsque le patient est au repos. Des mesures de la saturation en oxygène sont également effectuées en réaction à la détection d'un rythme cardiaque élevé. Ces mesures sont comparées aux mesures de référence en vue de distinguer les tachyarythmies ventriculaires stables et instables. On est en présence d'une tachyarythmie instable si l'on diagnostique une tachycardie tandis que le niveau présent de saturation en oxygène est similaire au niveau de saturation en oxygène moyen de référence ou si la saturation en oxygène telle qu'elle est mesurée sur le champ présente une caractéristique pulsatile diminuée par comparaison aux mesures de référence. Ledit dispositif de distinction est conçu por être utilisé conjointement avec ou en tant que partie d'un défibrillateur automatisé du type capable d'administrer diverses thérapies destinées à supprimer les tachyarythmies ventriculaires stables et instables, telles que la stimulation antitachycardique, la cardioversion et la défibrillation.
