Abstract: Systems and Methods for predicting patient health and patient relative well-being within a patient management system are disclosed. A preferred embodiment utilizes an implantable medical device comprising an analysis component and a sensing component further comprising a three-dimensional accelerometer, a transthoracic impedance sensor, a cardio-activity sensor, an oxygen saturation sensor and a blood glucose sensor. Some embodiments of a system disclosed herein also can be configured as an Advanced Patient Management System that helps better monitor, predict and manage chronic diseases.

Abstract: Methods and systems for providing a clinically modeled automatic diagnosis of patient health are disclosed. A preferred embodiment uses a medical device and network to analyze patient data in a manner consistent with a standard of medical care. Some embodiments of a system disclosed herein also can be configured as an Advanced Patient Management System that helps better monitor, predict and manage chronic diseases.

Abstract: An apparatus and method for adjusting the performance of an implanted device based on data including contextual information. Contextual information, including operational and performance data concerning the implanted device as well as the patient with the implanted device, is stored by a portable electronic device. In one embodiment, the portable electronic device is adapted for battery operation and includes a personal digital assistant (PDA). The portable electronic device is adapted for use as an interface to conduct wireless communications with the implanted device. In one embodiment, the portable electronic device interfaces with a clinical programmer for use by a physician.

Abstract: A method and apparatus for delivering anti-tachycardia pacing in an adaptive manner is disclosed. A cardiac rhythm management device, such as an implantable pacemaker, having anti-tachycardia pacing capability delivers anti-tachycardia pacing therapy in accordance with a selected pacing protocol upon detection of a terminable arrhythmia. The protocol is selected from a library of available protocols. A record of the successes and failures of each available protocol in converting tachyarrhythmias is maintained in a result table for use in selecting the protocol.

Abstract: An implantable cardioverter/defibrillator with antitachycardia pacing capability and method for operating same in which the detection zone boundary used to discriminate between tachycardia and fibrillation is adaptively adjusted based upon operating experience. Rate zones are provided for further classifying detected episodes of tachycardia and fibrillation according to the certainty of their being correctly identified based upon past operating experience. Adjustments of the rate zones and the fibrillation detection zone boundary are made based upon the results of antitachycardia pacing in attempting to terminate arrhythmic episodes.
