Additional information was received from the manufacturing representative indicating that they were able to achieve 4 efficiency bars when they met with the patient on (b)(6).On (b)(6), the patient called saying that she can only achieve 2 bars.The patient started to first experience difficulty charging one month prior.The pocket was reported to be palpated and they could not recreate the shocking/jolting.Shocking and jolting always happens during impedance tests.The rep could located 4 efficiency bars but was extremely sensitive with movement.The voltage of the patient was lowered so she feels better in her head and there is no tingling but her tremors are more pronounced now that the voltage has been dropped some.

Event Description

Additional information was received from the patient.Patient reported that they were not getting maximum benefit fromm ins therapy like they were before, further stating shaking in right hand, reacting negatively to a lot of things happening in the brain.Patient reported funny feelings in their head like too much electricity.Prior to the report, patient met with the health care professional (hcp), surgeon and manufacturer's representative (rep), and it was stated that programming was performed , hcp turned ins off and turned it back on a low setting between 50-75 when recharging which helped with the electricity in the patient's head.Patient reported they felt a terrible shock during the programming session while the doctor was trying to adjust the ins, and it was reviewed that they may have been part of the process to check/program the device.An x-ray mammogram was reported to be related to this issue.Patient reported that during the mammogram, their ins was hit and they had a black and blue spot on the chest after, further stating that they think the adverse events reported were related to the mammogram.Patient was redirected to follow up with hcp for continued troubleshooting if desired.Patient reviewed that the surgeon did not wish to operate unless necessary due to the patient's age.Patient reported that programming changes had helped and they could live with their current symptoms since they are retired, but was not getting the maximum benefit they were before.Patient also reported a heart attack sensation.Patient reported chest pain from the ins area (left side) radiating to the left and kind of felt like it was their heart, further stating the first occurrence lasted 30 minutes, patient went into hospital and had a heart work up and nothing was wrong, second occurrence lasted 5 minutes ,patient had a heart monitor they used and everything was normal with their heart.Patient also reported pain/ discomfort at the ins site.Patient was redirected to follow up with hcp to assess the ins/lead for this reaction.It was also stated that the ins had to be implanted on the left side as patient had a mastectomy on the right side so the ins could not be placed on that side.No further patient complications were reported/ anticipated as a result of this event.
