Information

EOL Indication

EOL device status is defined as three months following an ERI indication assuming the following post-ERI conditions: 100% VVI pacing at 60 ppm, 3 V, 0.4 ms; 500 Ohm pacing load; and six 30 J charges. EOL may be indicated before the end of three months if the device exceeds these conditions.
