The “ERI mode” varies according to theprogrammed pacing mode and is indicated by the pulse generator.CautionHigh output settings combined with very low lead impedance mayreduce the life expectancy of the pulse generator to less than1 year. Programming of pulse amplitudes, higher than 4.8 V, incombination with long pulse widths and/or high pacing rates canlead to premature activation of the replacement indicatorTable 33 shows the expected longevity (in years) from BOS to ERI forEstella pulse generators. The programmer software for the Estellapulse generators provides an estimated time to ERI in months and yearsthat is updated each time the device is reprogrammed. This estimationallows the physician to understand the longevity effects of modifyingprogrammed parameters.
