Event Type  Malfunction  
Event Description

The reporter indicated the pt was admitted to cardiac care unit for monitoring. The pt experienced an asystole and bradycardia, approx five or six mos ago. The pt was seen for video monitoring for his seizures. During the monitoring, the reporter noted that "the pt would go into "true persistent asystole with no pulse. " in addition, the pt had an asystole only during a magnet swipe which was set for 60 seconds on. The reporter stated the pt's magnet output current was set to 3. 5 ma. The reporter indicated the normal stimulation was set to 1. 5 ma. The reporter stated "the pt was having a seizure and they swiped the device initiating a magnet mode stimulation. " the reporter noted the asystole was longer, than when they swiped the pt without a seizure. The reporter stated "the asystole and bradycardia are directly related to vns stimulation. " during the pt's admission in the ccu, the reporter lowered the magnet output current to see how the pt would respond to the new settings. The reporter stated the pt was set to 2. 25ma. Thus, the pt no longer had asystole, but bradycardia. The reporter states "this setting does not help the pt's seizures to abort, but the cardiologist was fine with the bradycardia. " the reporter stated "the pt is fine now, just not getting as good of seizure control with the new setting. " good faith attempts to obtain additional info are in progress and awaiting results.
