ABSTRACT:
The cardiac rhythm management system includes an implantable medical device (IMD) with leads carrying electrodes for sensing cardiac electrical activity, and a physiologic sensor for sensing cardiac mechanical activity. The IMD measures electromechanical delays between electrical activity sensed by the electrodes and mechanical activity sensed by the physiologic sensor. The measured electromechanical delays can be used to detect lead dislodgement and to assess dyssynchrony between two areas of the heart, such as the right ventricle and the left ventricle.
