20080234774 | CLOSED-LOOP CONTROL OF CARDIOPROTECTIVE PRE-EXCITATION PACING - 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. | 09-25-2008 |
20100023082 | INDIVIDUALIZED MORPHOLOGY FEATURE EVALUATION AND SELECTION FOR DISCRIMINATION IN IMPLANTABLE MEDICAL DEVICES - 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. | 01-28-2010 |
