available settings for the Stratos CRT-Ps, see Section 11. 
2.1 Pacing 
Modes 
For a complete list of pacing modes available in each 
Stratos CRT-P configuration, see Section 11.1. 
2.1.1 Rate-adaptive Modes 
The rate-adaptive modes are designated with an “R” in the fourth 
position of the NBG pacemaker code on the programmer screen.  
The rate-adaptive modes function identically to the 
corresponding non-rate-adaptive modes, except that the basic 
rate increases when physical activity is detected by the motion 
sensor. 
In demand modes (i.e., DDDR, DDIR, DVIR, VDDR, VVIR, 
AAIR), it is possible that the atrial and/or ventricular refractory 
period can comprise a major portion of the basic interval at high 
sensor-modulated rates.  This may limit the detection of 
spontaneous events or even exclude their recognition altogether.

Rate Adaptive Pacing – Use rate-adaptive pacing with care 
in patients unable to tolerate increased pacing rates. 
 
2.1.2 DDD 
The timing of the Stratos CRT-Ps is based on atrial events. 
In the case of an atrial sensed or paced event, the AV delay 
starts the same time as the basic interval.  If a ventricular sensed 
event does not occur within the AV delay, ventricular pacing is 
initiated at the end of the AV delay.  If ventricular sensing occurs 
within the AV delay, ventricular pacing is inhibited. 
If atrial sensing occurs outside the atrial refractory period, atrial 
pacing is inhibited and the basic interval is restarted.
