Non-invasive detection of phrenic nerve stimulation

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] Cross References to Related Applications [0002] This application claims the benefit of U.S. Patent Application Serial No. 14 / 220,733, filed March 20, 2014, and entitled "Non-Invasive Detection of Phrenic Nerve Stimulation," which is incorporated by reference It is hereby incorporated in its entirety. Background technique [0003] 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. [0004] Cardiac pacing electrodes may be used in various systems, devices, and methods for medically treating a patient. More specifically, cardiac pacing electrodes may be positioned adjacent to or in c...

AI Technical Summary

Problems solved by technology

Some electrodes and / or electrical pacing vectors used for cardiac pacing therapy may inadvertently or inadvertently stimulate the patient's phrenic nerve, e.g. causing undesired diaphragm movement, patient discomfort, etc.
