    摘要: Systems and methods for evaluating a patient condition using autonomic balance information involve providing an implantable cardiac device that acquires a cardiac waveform from a patient. One or more characteristics associated with autonomic balance of the patient are detected and used to evaluate a patient condition, such as sleep onset, sleep stage, cardiac vulnerability over a predetermined duration, and sleep disordered breathing. Patient activity levels may be sensed and used to evaluate the patient's condition, such as for determining a level of systemic stress. Characteristics associated with the autonomic balance include calculating an LF/HF ratio waveform and/or determining one or more morphological features of the LF/HF ratio waveform. Coordination with a patient-external device may facilitate transmission of information about one or more of the cardiac waveform, the one or more characteristics associated with the autonomic balance, and a marked cardiac waveform.

    摘要: A cardiac rhythm management system for providing a plurality of therapy modalities. For example, the system may include a cardiac resynchronization therapy module for providing cardiac resynchronization therapy and a pacemaker module for providing bradycardia therapy, as well as a selector module coupled to the cardiac resynchronization therapy module and the bradycardia module. The selector module may select an operating mode from among a plurality of operating modes including the cardiac resynchronization therapy module and the pacemaker module. Various manual and automatic methods may be used to select the operating mode. In addition, a reversion management system may be included to assist the cardiac rhythm management system to recover in case of a disruption to the system.

    摘要: A method for operating a cardiac rhythm management device in which a clinical state vector is computed as a combination of a plurality of parameters related to a patient's heart failure status and compared to a previously computed clinical state vector to determine a clinical trajectory indicative of changes in the patient's heart failure status. Such detected changes in status can be used both as a clinical tool to evaluate treatment and to automatically adjust the operation of the device.

    摘要: A method and device for delivering cardiac function therapy on a demand basis. An implantable device for delivering cardiac function therapy is programmed to suspend such therapy at periodic intervals or upon command from an external programmer. Measurements related to hemodynamic performance are then taken using one or more sensing modalities incorporated into the device. Based upon these measurements, the device uses a decision algorithm to determine whether further delivery of the cardiac function therapy is warranted.
