Event Description

Data was received and reviewed for the patient's generator.The battery voltage dropped to ifi (intensive follow-up indicator) remaining shortly after the removal of the 0.5 v offset due to the battery reaching the 7.5% threshold.No rebound has been observed at this time.Based on the charge consumption, it is not expected that the generator would be at ifi battery remaining.This is not indicative of a device failure but a normal design of the device.The impedance history was reviewed no issues were seen.No other anomalies were noted in the decoder review.Based on the data review, this appears to be a case of the bol battery impedance causing the generator to display battery at ifi when in reality the generator battery voltage is not low.
