摘要： A system comprises an implantable medical device (IMD), a external user interface device, and a radio frequency link quality assessment (LQA) device. The external user interface device and the IMD are adapted to potentially use one or more of a plurality of available wireless communication channels to communicate. The LQA device is positioned to receive a radio frequency communication between the IMD and the external user interface device. At least one of the IMD, the external user interface device, and the LQA device is adapted to evaluate signal and noise strength of the available channels to determine respective signal and noise levels for each channel by using the noise level for the target channel and interference potential for corresponding adjacent channels to the target channel as inputs to a function to provide a value for a LQA for the target channel, and select a preferred communication channel based on the LQA value for each of the available wireless communication channels.

An embodiment of the method includes measuring a plurality of available wireless communication channel potentially used to communicate between an implantable medical device (IMD) and a programmer to determine signal and noise levels for the channels. The method also includes storing the signal and noise levels. The method further includes processing the stored levels to determine the interference potential on the channels adjacent to the available channels. In this embodiment, the method also includes selecting a preferred communication channel based on a function of noise level for a target center channel and interference potential for corresponding adjacent channels to the target channel. Other aspects and embodiments are provided herein.

摘要： An implantable cardiac rhythm management device operable in an autothreshold or autocapture verification mode, wherein the rhythm management device is capable of detecting noise that affects signal characteristics of a sensed intracardial evoked response electrogram signal. The device includes a noise detection circuit that determines whether a minimum peak timing occurs during a predetermined time following delivery of a stimulation pulse. If a minimum peak timing occurs during the predetermined time following delivery of the stimulation pulse, then significant amounts of noise affecting the signal characteristics of the electrocardiogram signal is assumed.
