| 20110066055 | SYSTEM AND METHOD FOR USE WITH AN IMPLANTABLE MEDICAL DEVICE FOR DETECTING STROKE BASED ON PHYSIOLOGICAL AND ELECTROCARDIAC INDICES - Techniques are provided for detecting stroke within a patient using an implantable medical device. In one example, various electrocardiac and physiological signals are sensed within the patient by the implantable device. The device derives a set of indices from the sensed signals based on parameters affected by stroke. Stroke is then detected within the patient based on an examination of the set of indices. Warnings can then be generated, neurostimulation delivered, pacing therapy adjusted, medications dispensed, etc., in response to the stroke. In one particular example, the set of indices includes: a heart rate variability index; a heart rate turbulence index; a baroreflex index; a QT index; a respiration index; and a circadian variability index, from which a composite stroke index is derived. Time delta indices may also be generated for each individual index, which are exploited in generating the composite stroke index. | 03-17-2011 |

| 20100010555 | SYSTEM AND METHOD FOR CONTROLLING A HEART STIMULATOR - In a system and method for controlling an implantable stimulator capable of producing pacing pulses to be delivered to cardiac tissue, as well as vagal stimulation pulses to be delivered to vagus nerve sites, upon detection of a premature cardiac event, such as a premature ventricular or atrial contraction, a simulated heart rate turbulence (HRT) procedure is applied if the intrinsic heart rate turbulence is weakened or absent. The simulated HRT includes a first phase in which the heart rate is increased, from the existing level, for a number of heart beats, a second phase in which the heart rate is decreased for a number of heart beats, and an optional third phase in which the heart rate is returned to said existing level. | 01-14-2010 |

| 20110196441 | SYSTEMS AND METHODS FOR OPTIMIZING MULTI-SITE CARDIAC PACING AND SENSING CONFIGURATIONS FOR USE WITH AN IMPLANTABLE MEDICAL DEVICE - Techniques are provided for use with an implantable cardiac stimulation device equipped for multi-site left ventricular (MSLV) pacing using a multi-pole LV lead. In one example, referred to herein as QuickStim, cardiac pacing configurations are optimized based on an assessment of hemodynamic benefit and device longevity. In another example, referred to herein as QuickSense, cardiac sensing configurations are optimized based on sensing profiles input by a clinician. Various virtual sensing channels are also described that provide for the multiplexing or gating of sensed signals. Anisotropic oversampling is also described. | 08-11-2011 |
