摘要： Methods, Implantable Pulse Generators (IPGs), and systems for stimulating a sympathetic nervous system nerve including automatically increasing the maximum stimulation current intensity over time. Some IPGS increase the current stimulation current maximum upon passage of an elapsed time or occurrence of a time of day. The current stimulation current maximum is the actual stimulation current in some methods and is a ramp maximum in other methods. The patient may interact with the IPG to indicate discomfort, resulting in a decrease in the current stimulation current maximum. In some methods, after receiving too many patient indications of discomfort, stimulation is stopped by the IPG.

摘要： An implantable cardiac rhythm management (CRM) device includes a sensing and detection circuit that senses at least one cardiac signal and detects cardiac electrical events from the sensed cardiac signal using a detection threshold that is adjusted based on a dynamic noise estimation. The sensed cardiac signal is filtered to produce a filtered cardiac signal having a signal frequency band and a noise signal having a noise frequency band. The noise frequency band is substantially different from the signal frequency band. A dynamic noise floor is produced based on the noise signal and used as the minimum value for the detection threshold. A cardiac electrical is detected when the amplitude of the filtered cardiac signal exceeds the detection threshold.

摘要： Methods and devices for classifying a cardiac response to pacing involve establishing a retriggerable cardiac response classification window. A first cardiac response classification window is established subsequent to delivery of a pacing pulse. A cardiac signal following the pacing stimulation is sensed in the first classification window. A second cardiac response classification may be triggered if a trigger characteristic is detected in the first classification window. The cardiac signal is sensed in the second classification window if the second classification window is established. The cardiac response to the pacing stimulation is determined based on characteristics of the cardiac signal. The cardiac response may be determined to be one of a captured response, a non-captured response; a non-captured response added to an intrinsic beat, and a fusion/pseudofusion beat, for example.
