It was reported that an asymptomatic patient presented in-clinic for a scheduled follow up.Upon interrogation, it was revealed that the device was experiencing a combination of competitive atrial pacing and intermittent atrial undersensing.There were large number of auto mode switch episodes which appeared to be caused by competitive atrial pacing as well as intermittent atrial undersensing of true atrial fibrillation that was causing the device to go into and out of ams regularly.The atrial sensitivity was reprogrammed.Post ventricular atrial refractory period (pavrp) was not reprogrammed.The patient was stable prior, during and post procedure.The patient will continue to be monitored.
