Upon receipt, the device interrogation revealed the battery status eri, which was triggered on (b)(6) 2015.At a first step the ability of the device to deliver therapies was verified.The antibradycardia pacing pulses proved to be normal and in amplitude and frequency as programmed.There was no indication of a device malfunction.The programmed parameters were inspected.It was noted, that the left ventricular pacing output was temporarily programmed to 4.0 v for 1.5 ms.This represents a high current program, draining the battery.The device was implanted for 32 months.Taking the high current program for crt pacing into account, the eri condition was found to be anticipated.In conclusion, the pacemaker was fully functional.The battery status was anticipated.Biotronik monitors the post-market performance of its products closely in order to identify any trends that may reveal over time a potential manufacturing or design issue.The historic performance of the product involved in the current case does not at this point reveal any such trend.For this reason we encourage close dialogue between clinicians and our product experts in order to explore all options to minimize any such occurrences in future.
