It was reported that high impedance was observed 15 days following generator replacement.X-rays were taken and sent to manufacturer for review.Review of x-rays were unable to determine whether or not the lead pin was fully inserted into the generator header due to the angle of the images.There were no obvious discontinuities in the portion of the lead that could be seen.The presence of a micro-fracture in the lead also cannot be ruled out.It was reported that the patient was seen by the surgeon at which time high impedance was again confirmed.The patient was scheduled for revision surgery.It was reported that the lead pin would be reinserted into the generator header; however, if this does not resolve the high impedance then lead revision would be performed.No known surgical interventions have been performed to date.
