Footnote

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

Information

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% VVI pacing at 60 min-1, 2.5 V 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.
