Semi-annual 5.7 7.0 8.3 9.0

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; Optivol ON; Atrial Fib percentage of time 0%; Charging frequency assumes maximum energy charge and includes therapy shocks and capacitor formation.

EOS Indication

The Prolonged Service Period (PSP) is the time between the RRT and EOS. The PSP is defined as 3 months assuming the following conditions: 100% DDD pacing at 60 min-1, 2.5 V atrial and RV pacing amplitude; 0.4 ms pulse width; 600 Ω pacing load; and 6 full-energy charges. The EOS may be indicated before the end of 3 months if the device exceeds these conditions.
