    摘要： Cardioprotective pre-excitation pacing may be applied to stress or de-stress a particular myocardial region delivering of pacing pulses in a manner that causes a dyssynchronous contraction. Such dyssynchronous contractions are responsible for the desired cardioprotective effects of pre-excitation pacing but may also be hazardous. Described herein is a method and system that uses measures of ventricular dyssynchrony or a patient's physiological response to ventricular dyssynchrony to control the delivery of cardioprotective pre-excitation pacing in closed-loop fashion.

    摘要： Cardiac devices and methods provide adaptation of detection windows used to determine a cardiac response to pacing. Adapting a detection window involves sensing a cardiac signal indicative of a particular type of cardiac pacing response, and detecting a feature of the sensed cardiac signal. The cardiac response detection window associated with the type of cardiac pacing response is preferentially adjusted based on the location of the detected cardiac feature. Preferential adjustment of the detection window may involve determining a direction of change between the detection window and the detected feature. The detection window may be adapted more aggressively in a more preferred direction and less aggressively in a less preferred direction.

    摘要： A method and system for dynamically balancing a rotating system or rotating device utilizing data collection and correlation techniques to extract balance measures from sensor data is disclosed. Sensor data from the rotating system, containing information indicative of the dynamics of the rotating system, are filtered and sampled. A select time span of sampled data, adjusted upward to a nearest number of full revolutions of the rotating system, which is of sufficient size to extract balance measures, is collected. Data may be collected as a fixed number of samples per revolution, independent of a rotational speed, so as to simplify later computation. Several unique select time spans may be used for different ranges of rotational speeds so as to maintain the amount of data to be processed while still serving its original purpose. Window function may be applied to modify sampled data in the select time span so as to improve extraction performance. The fixed select time spans of sampled data provide for a fixed bandwidth correlation-based computation to extract desired balance measurements. The balance measures are used to assess the balance state of the rotating system and update control models so as to determine the proper course for balancing corrections necessary to dynamically place the rotating system in a balanced state.

    摘要： An apparatus comprises an implantable sensor, which provides a plurality of physiologic sensor signals of a subject, and a processor. The processor includes a feature module and a detection module. The feature module is configured to identify a feature in the sensor signals and to determine a measure of quality of the feature in the sensor signals. The detection module is configured to perform a morphology analysis of a subsequent portion of at least one of the sensor signals using the feature when the measure of quality of the feature satisfies a quality measure threshold.
