17. STANDBY MODE
Standby is a safety mode of operation that the pacemaker enters in response to a failure
of one of the self-tests that are performed periodically. The programmer has the ability to
examine the pacemaker by telemetry and restart or, if possible, re-initialize the pacemaker.
Test modes, including magnet mode, are disabled and statistics are not incremented. In
standby mode, programming is not possible and the device functions as follows:
Mode VVI*
Basic rate 70 ppm
Rate hysteresis 0%
Pulse amplitude 5 V
Pulse width 0.50 ms
Sensitivity 2.2 mV
Polarity (pacing and sensing) Unipolar
Rate smoothing OFF
Rate-responsive mode OFF
Remote monitoring OFF
*VVI mode for the DR model and the SR model when implanted in the ventricle or AAI for the
SR model when implanted in the atrium
NOTE:
Pacing thresholds do not vary significantly for pulse widths ranging from 0.5 ms to 1 ms, so
a 0.50 ms pulse width has been selected to save energy.
