 If 90% of the maximum sensor rate is reached for 1 hour
within 24 hours, gain is reduced by one step.
2.9.12 Pulse Amplitude
The Pulse Amplitude parameters, are separately programmable
for atrial and both ventricular channels and they, define the
amplitude in volts of the pacing pulses. The pulse amplitude is
also independently programmable for normal bradycardia pacing
and fixed to 7.5V for post-shock pacing in RA and RV and as
permanent programmed in LV.
2.9.13 Pulse Width
The Pulse Width parameters are separately programmable for
atrial and both ventricular channels and they define the duration
of the pacing pulses. The pulse widths are also independently
programmable for normal bradycardia pacing and fixed to 1.5 ms
for post-shock pacing in RA and RV and as permanent
programmed in LV.
2.9.14 Post Ventricular Atrial Refractory Period
DR and HF versions only
Immediately following each paced ventricular event, an atrial
refractory period is started; this period is called Post Ventricular
Atrial Refractory Period or PVARP. Atrial signals are ignored
during this time for bradycardia timing purposes to prevent the
ICD/CRT-D from sensing inappropriate signals.
2.9.15 PVARP after VES
DR and HF versions only
This parameter extends the Post Ventricular Atrial Refractory
Period by the programmed interval, if the ventricular event is not
followed by an atrial sensed event (VES).
