    Additional Manufacturer Narrative · 1

    LABORATORY ANALYSIS DETERMINED THAT THIS DEVICE EXPERIENCED NORMAL BATTERY DEPLETION, BUT THE DEVICE REACHED EOL EARLIER THAN EXPECTED DUE TO A CHANGE IN BATTERY CURRENT CONSUMPTION. IN SOME CIRCUMSTANCES, THIS CHANGE MAY ALSO CAUSE A REVISION OF THE POINT IN BATTERY LIFE AT WHICH THE DEVICE WILL DECLARE ERT IN ORDER TO ENSURE 3 MONTHS OF BATTERY LIFE BETWEEN ERT AND EOL. THIS ERT DECLARATION POINT AND ASSOCIATED ESTIMATE OF TIME TO ERT DEPEND ON DEVICE OPERATING CURRENT AND BATTERY DEPLETION TO DATE. FACTORS INFLUENCING OPERATING CURRENT INCLUDE PACING RATE, AMPLITUDE, PULSE-WIDTH, LEAD IMPEDANCE, AND THE LAST 30 DAYS AVERAGE PACING PERCENTAGE. DEVICE REPROGRAMMING AFFECTING PACING DEMAND, TEMPORARY AMBULATORY SUSPENSION OF THE RV PACE AUTO CAPTURE FEATURE, AND GRADUAL CHANGES IN LEAD IMPEDANCE ARE SOME FACTORS AFFECTING OPERATING CURRENT WHICH MAY CAUSE A REVISION TO THE ERT DECLARATION POINT. THE ESTIMATED LONGEVITY REMAINING AND BATTERY STATUS GAUGE DISPLAYED BY THE PROGRAMMER ARE BASED ON BATTERY CURRENT CONSUMPTION CALCULATIONS AT THE TIME OF INTERROGATION, AND CALCULATIONS PERFORMED INTERNAL TO THE DEVICE ARE SUSPENDED DURING THE SESSION. WHEN AMBULATORY (AWAY FROM THE PROGRAMMER), THE DEVICE PERIODICALLY ASSESSES OPERATING CURRENT AND MAY REVISE THE ERT DECLARATION POINT TO ENSURE A MINIMUM OF 3 MONTHS BATTERY LIFE BETWEEN ERT AND EOL. THIS DEVICE ASSESSMENT OF OPERATING CURRENT, BATTERY CHARGE STATE, AND REVISION OF THE ERT DECLARATION POINT MAY CAUSE DIFFERENCES AND FLUCTUATIONS RELATIVE TO PREVIOUS PROGRAMMER BATTERY STATUS INDICATORS.
