It was reported that a pt developed drop attacks in 2009 (approximately 7.
5 years after being implanted which lead to the pt being hospitalized.
The pt also had periodic bradycardia.
The device was programmed off and the bradycardia and drop attacks resolved.
Additional information received from the pt's physician revealed that the pt does not have a history or a family history of cardiac events.
The pt presented with syncope which suggested some sort of arrhythmia.
The pt's heart rate prior to the event was 70 and decreased to 10 during the event.
The blood pressure was 120/80 prior to the event; however, no blood pressure readings were provided after the event.
There were no traumatic events, medication changes, or triggers such as smoking, caffeine intake, etc.
That preceded the onset of the bradycardia.
The pt is currently taking zonegran, lamictal, and topamax.
The bradycardia did not occur during device diagnostics nor did it occur following a setting change.
An ecg and polysomnography were performed to diagnosed the arrhythmia.
The arrhythmia (bradycardia) is believed to be related to device stimulation and is exaggerated by the device.
The pt was hospitalized for the length of testing needed to diagnose the arrhythmia.
The arrhythmia has not recurred since the device has been programmed off.
Good faith attempts to obtain additional information are currently being made.
