It was reported that during a follow up in clinic, inappropriate automatic mode switch (ams) and variable autocapture trend were noted on the device.Abbott technical support was contacted, the session records were reviewed, and the inappropriate ams was found to be due to competitive atrial pacing (cap).Additionally, during the autocapture threshold tests the threshold was unable to be found resulting in out of range measurements, however, otherwise the threshold was stable.One instance of cap was found to have been initiated by the autocapture threshold test.Reprogramming of the device was recommended.No intervention has been performed at this time.The patient was in stable condition and will continue to be monitored.
