Adaptive phrenic nerve stimulation detection

摘要: An example of a system comprises cardiac pulse generator configured to generate paces pace the heart, sensor sense physiological signal for use in detecting pace-induced phrenic nerve stimulation (PS), storage, and detector. The storage is store patient-specific PS features beats with desirably large signal-to-noise ratio. detector may be detect patient by analyzing beat ratio induced using pacing energy output stored memory when heart paced pulses smaller output.
