Event Description

It was reported that a vns pt rec'd a high impedance warning during device diagnostic testing. The pt's treating vns therapy physician indicated that the pt had been unable to perceive vns stimulation and that her lead had recently become visible under the skin of her neck prior to receiving high impedance results. The physician indicated that device diagnostics had been performed a month prior to these results and had confirmed proper device function, and the pt experienced a tonic clonic seizure prior to the onset of these events, but that she was unsure whether this has been a contributing factor. X-rays of the pt's device were rec'd and during a review of these images, it was identified that the pt's lead connector pin did not appear to have been fully inserted within the generator's connector block. The pt will reportedly undergo exploratory surgery by the end of the month.
