Estimated Longevity

Charging Frequency 100% Pacing 50% Pacing 15% Pacing 100% Sensing
Monthly 3.7 4.1 4.3 4.5
Quarterly 5.3 6.1 6.8 7.1
Semi-annual 6.0 7.0 8.0 8.5

Longevity estimates based on the following device usage. Pacing Mode DDD; Atrial Lower Pacing Rate 60ppm; Ventricular Lower Pacing Rate 60ppm; Atrial Pulse Width 0.4ms; Ventricular Pulse Width 0.4ms; Atrial Pulse Amplitude 3V; Ventricular Pulse Amplitude 3V; Atrial Impedance 510ohms; Ventricle Impedance 510ohms; Atrial Sensing Rate 70bpm; Ventricle Sensing Rate 70bpm; EGM prestorage OFF; Atrial Fib percentage of time 0%; Charging frequency assumes maximum energy charge and includes therapy shocks and capacitor formation.

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.
