Abstract

In an example of a method, the method includes testing for phrenic nerve stimulation (PS) threshold. If PS beats are detected at the pacing output level, analyzing the detected PS beats using criteria to determine if the pacing output level can be declared to be the PS threshold. If the pacing output level cannot be declared to be the PS threshold based on the analysis of the PS beat at the pacing output level, performing a PS beat confirmation procedure. The PS beat confirmation procedure may include delivering additional cardiac paces at the pacing output level to generate additional PS beats, and analyzing the detected PS beats using other criteria to determine if the pacing output level can be confirmed as the PS threshold.

First claim

What is claimed is:

1. A method, comprising:
testing for phrenic nerve stimulation (PS) threshold, including:
pacing a heart with cardiac paces at a pacing output level;
sensing a physiological signal for use in detecting PS beats, wherein the PS beats are cardiac paces that induce phrenic nerve stimulation; and
monitoring for PS beats in the sensed physiological signal to detect if the pacing output level causes PS beats;

if PS beats are detected at the pacing output lev…
