Event Description
|
During a programming history database periodic review, high impedance was found for this patient.The impedance later resolved and has been within normal limits ever since.Generator was noted to be explanted, but no device has been received to date.It is assumed that the device has been discarded.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.Dhr review for the generator was performed.The generator passed final functional and quality specifications prior to release for distribution.No further relevant information has been received to date.
