Systems and methods for evaluating multiple candidate sensing vectors for use in sensing electrical activity of a heart are disclosed. The system can sense physiologic signals using each of a plurality of candidate sensing vectors, and generate respective signal intensity indicators and interference indicators using the physiologic signals sensed by using the respective sensing vectors. The system can also receive electrode information of each of the candidate sensing vectors, including information about sensing electrodes that are also used for delivering cardiac electrostimulation. The system can rank at least some of the plurality of candidate sensing vectors according to the signal intensity indicators, the interference indicators, and the electrode information. The system can also include a user interface for displaying the ranked sensing vectors, and allowing the user to select at least one sensing vector for use in sensing the cardiac electrical activity.

System and methods for sensing vector selection

An example of a method performed by an implantable medical device (IMD) to deliver a therapy to a patient may include delivering the therapy to the patient, detecting a trigger that is controlled by the patient or a caregiver to the patient, and determining if at least one feature of the IMD for responding to a trigger is enabled. The IMD may be configured to allow the patient or the caregiver to the patient to enable the at least one feature. The method may further include, when the at least one feature is enabled, automatically implementing the at least one enabled feature in response to the detected trigger, including automatically suspending the therapy in response to the detected trigger and automatically restoring the therapy after a defined period after the detected trigger.

Systems and methods for a configurable programmer for an implantable cardiovascular medical device are disclosed. A preferred embodiment comprises a graphical user interface to visualize programming processes to alert a clinician to potential problems with the patient's condition or the therapy provided by the device, or the device itself. The programmer is further adapted to minimize the risk of programming potentially dangerous changes to the implantable device's parameter settings by requiring the clinician to first review new value changes before initiating the programming step. The programmer also allows the clinician to view how a change to one or more parameter settings affect other settings before the implantable device is programmed or re-programmed.

Implantable medical device programming apparatus having a graphical user interface

A medical device programmer automatically adjusts parameters to be programmed to a medical device in response to a user modifying related parameters. Slide controllers on the programmer display screen can adjust parameters. In response to slide controller movement, the programmer automatically adjusts related parameters by moving their slide controllers. This graphically illustrates to the user the automatic adjustments being made to the related parameters. and the relationship between parameters being adjusted by the user and automatically. In response to on screen parameter changes, the system graphically illustrates the parameter values that are changed and those that are programmed to the medical device and those that would cause unsafe condition in the medical device if programmed. The method also prevents the programming to the medical device the parameters that would cause an unsafe condition.

This document describes systems, devices, and methods for programmably adjusting therapy or other operative parameter values of an implantable cardiac rhythm management device using a programmer that includes a display that graphically illustrates one or more relationship between a parameter being programmed and other parameters and/or rules governing interactions between parameters.
