Event Description

Information was received that a vns patient was admitted to hospital for bradycardia and syncope. It was reported that the patient has recently had many episodes of syncope. They also noticed the patient had pauses on the cardiac monitoring. These pauses are erratic, lasting about 3 sec and does not coincide with stimulation. They placed the magnet over the generator for 24 hours and during that time, they didn't see anymore cases of heart pauses. No vns setting changes were made prior to the onset of the events. The patient was set at 1. 25/30/250/21/0. 5 so, a 49% duty cycle. The patient was discharged from the hospital on (b) (6), and there were no further incidents of the heart pauses or syncope, and the event was not duplicated again on the cardiac monitoring equipment. The cardiologist recommended having the patient wear a holter monitor for 20 days to monitor cardiac activity, and will re-assess the patient at that time. The device remains programmed on and per the physician he tested the device following the onset of the events, and it is operating within normal limits. The cause of the syncope and the irregular heart pauses is unknown at this time. It was reported that the patient had a myocardial infarction (mi) in (b) (6) 2010, and at that time he was put on a beta blocker medication. It is unknown if stimulation may be a contributory factor to the recent events, but their treating physician should have more information after (b) (6). Good faith attempts to obtain additional details have been unsuccessful to date.
