Programming Requirements and Restrictions
The following requirements and restrictions insure that parameter settings selected for programming
do not form an invalid combination or cause an undesirable interaction. An invalid combination of
pending parameter values is indicated when the pending values of the parameters involved appear on
the screen in reverse video (see pages 6-3 and 6-4). Programming will not be allowed until valid
parameter values have been selected.
Parameter Programming Restriction/Requirement
Atrial Blanking Atrial Blanking cannot be greater than PVARP.
Atrial Blanking must be at least 50 ms shorter than Atrial Refractory.
The programmed value for Atrial Blanking cannot be changed when Mode Switch is ON.
Lower Rate Lower Rate must be less than Upper Activity Rate and/or Upper Tracking Rate.
The following combinations of Lower Rate and Paced AV Interval cannot be
programmed:
Lower Rate Paced AV Interval
140 ppm 340 - 350 ms
145 330 - 350
150 310 - 350
155 300 - 350
160 290 - 350
165 280 - 350
170 260 - 350
175 250 - 350
180 240 - 350
Pacing Mode If an interrogation for the present parameter settings has not occurred, the programmer will
not allow you to program a pacing mode unless you also select values for certain other
parameters, such as Lower Rate. Interrogating the pacemaker from the Pacing Parameters
screen eliminates this requirement.
Mode Switch Certain parameter values automatically are made pending when you select ON as the
Mode Switch value:
■ Upper Activity Rate is set equal to Upper Tracking Rate.
■ Rate Adaptive AV Interval is set to ON.
■ Atrial Blanking is set to a value based on the Upper Tracking Rate and PVARP is set
to a value based on the Detect Rate. If the pacing mode is VDD, PVARP is set to
“varied.”
Upper Tracking Rate cannot be less than 100 ppm.
Lower Rate cannot be less than 35 ppm or greater than 100 ppm.
Sensed AV cannot be less than 40 ms or greater than 160 ms.
