Abstract
A system and method are described for automatically detecting diaphragmatic stimulation (DS) based on evoked response signals, electrogram data and/or thoracic impedance measurements. In addition, several optional modalities are described to circumvent this problem and alleviate symptoms related to DS while preserving LV pacing.
Claims18
A method for detecting diaphragmatic stimulation comprising:
- delivering a stimulation pulse to a patient's heart;
- sensing an electrogram signal of the heart resulting from the stimulation pulse;
- and
- analyzing the sensed electrogram signal of the heart to detect diaphragmatic stimulation that is induced by the stimulation pulse delivered to the heart.

A system for detecting diaphragmatic stimulation comprising:
- means for delivering a stimulation pulse to a patient's heart;
- means for sensing an evoked response electrical potential signal of the heart resulting from the stimulation pulse;
- and
- means for detecting diaphragmatic stimulation that is induced by the stimulation pulse delivered to the heart, based on the sensed evoked response electrical potential signal of the heart.
