Abstract

Displacement or migration of a left ventricular lead located within the coronary sinus or coronary veins of the heart is detected by comparing an electrogram (EGM) waveform pattern from the lead with a stored baseline EGM waveform pattern. Based upon the extent of lead migration, if any, a lead displacement may produce an annunciating response. The patient may be alerted, an electrical stimulus applied through the lead may be adjusted to compensate for lead migration, or an alternative electrode on the lead may be used for EGM sensing and pacing.
