It was reported that a patient's device was showing high impedance.The patient was recently implanted with an impedance with ok impedance.It was further noted that the patient was experiencing an increase in seizures.X-rays were received but could not properly assess complete pin insertion or fracture due to image quality.An update was received that impedance was back within normal limits.No intervention was planned to date.It was noted that testing could not be performed with the patient at different conditions due to the patient's condition.Internal investigation identified that a change in the timing of the impedance test may result in higher impedances for model 1000 generator compared to those reported by model 103-106 generator.As indicated in the physician's manual, high lead impedance (>/= 5300 ohms), in the absence of other device-related complications, is not an indication of a lead or generator malfunction.No relevant surgical intervention has occurred to date.At the time of this report it is unclear whether this event is related to this "m1000 higher impedances" issue mentioned above.No additional relevant information was received to date.
