    • A method and apparatus for varying a parameter in an implantable medical device that includes a plurality of electrodes stimulating heart tissue and sensing cardiac signals, a timing and control device controlling the stimulation of heart tissue by the plurality of electrodes and measuring intervals between the sensed cardiac signals, a storage device storing the measured intervals, and a microprocessor. The microprocessor determines heart rate variability in response to the stored intervals, compares the determined heart rate variability to a predetermined target rate profile, adjusts the parameter from a first setting to a second setting different from the first setting in response to the comparing of the determined heart rate variability and the predetermined target rate profile, and adjusts the parameter from the second setting to a termination setting in response to a termination event or expiration of a first predetermined time period.

    • A system and method for monitoring respiration including sensing a signal that varies with respiration, deriving a respiration parameter, applying criteria for detecting a respiration disturbance and determining one or more respiratory disturbance metrics. The system preferably includes an implantable sensor with an associated implantable medical device such that chronic respiration monitoring is possible. The implantable medical device may execute methods for detecting and measuring respiratory disturbances or may store data to be transferred to an external device for detecting and measuring respiratory disturbances. Respiratory disturbance detection may trigger a responsive action such as physiological data storage, a change in therapy delivery, or a clinician warning. Assessment of cardiac function may be made based on metrics of respiratory disturbances or a measure of circulatory delay time following detection of a respiratory disturbance.
    • 一种用于监测呼吸的系统和方法,包括感测随呼吸变化的信号,导出呼吸参数,应用用于检测呼吸障碍的标准和确定一个或多个呼吸障碍度量。 该系统优选地包括具有相关联的可植入医疗装置的可植入传感器,使得可以进行慢性呼吸监测。 可植入医疗装置可以执行用于检测和测量呼吸障碍的方法,或者可以将要传送到外部设备的数据存储以检测和测量呼吸障碍。 呼吸道干扰检测可能会触发响应动作,如生理数据存储,治疗传递的变化或临床医生的警告。 心脏功能的评估可以基于呼吸紊乱的度量或检测到呼吸障碍之后的循环延迟时间的量度进行。
