Abstract

Systems, methods, and graphical user interfaces are described herein for non-invasively detecting phrenic nerve stimulation during cardiac pacing therapy. Phrenic nerve stimulation information may be generated for one or more electrical pacing vectors at one or more power configurations. The phrenic nerve stimulation information may be displayed to a user for use in configuring and / or evaluating cardiac pacing therapy.

Description

[0001] This application is an invention patent application with the international application number PCT / US2015 / 021442, the international application date is March 19, 2015, and the application number entering the Chinese national phase is 201580025687.7, entitled "Non-invasive detection of phrenic nerve stimulation". divisional application. technical field [0002] The disclosure herein relates to systems and methods for non-invasive detection of phrenic nerve stimulation during delivery of cardiac pacing therapy. The systems and methods may monitor the patient's electrical activity during cardiac pacing therapy using a plurality of electrodes adjacent tissue of the patient, and may use the monitored electrical activity to determine whether the cardiac pacing therapy is stimulating the phrenic nerve. Background technique [0003] Cardiac pacing electrodes may be used in various systems, devices, and methods for medically treating a patient. More specifically, cardiac pacin...
