Manufacturer Narrative

If pertinent information is provided in the future, a supplemental report will be submitted.-- correction to section h: updated to reflect product return and pending analysis.The product has been received for analysis.This report will be updated upon completion of analysis.-- upon receipt at our post market quality assurance laboratory, this device was thoroughly inspected and analyzed.Interrogation of the device confirmed it was operating in safety mode, had undergone resets, and that bradycardia therapy remained available.Engineers determined that this device was demonstrating behavior consistent with a high internal cell impedance within the battery.The high internal impedance put this device at risk of experiencing transient voltage decreases (and associated resets) during periods of high-power consumption.When battery voltage drops below a minimum threshold, a system reset is performed.If three system resets occur within a 48-hour period, the device is designed to immediately enter safety mode operation to maintain back-up pacing with pre-defined, non-programmable settings.
