Automatic Pacing, Sensing, and Lead Monitor

Implant Detection and Initialization
At the completion of the 30-minute Implant Detection period, the appropriate pacing and sensing polarities are automatically selected by the device; Ventricular Output Management is enabled and Amplitude and Pulse Width become adaptive. Reduced VP™+ is enabled 60 minutes after Implant Detection is complete.

bTolerance for amplitudes from 0.5 V through 6.0 V is ± 10% and for 7.5 V is -20/+0%. Tolerances are based on 37°C and a 500Ω load. Amplitude is determined 200 μs after the leading edge of the pace.
