7. Programmable ParametersEstella Pulse Generators Technical Manual 45For a complete list of programmable parameters and the availablesettings, see Section 15.7.1 Pacing ModesFor a complete list of pacing modes available in each Estellaconfiguration, see Section 15.1.NOTE:Ventricular Capture Control is only available with the followingpacing modes: DDDR, VDDR, VVIR, DDD, VDD, VVI, DDD-ADI andDDDR-ADIR.7.1.1 Motion Based Rate-Adaptive ModesThe motion based rate-adaptive modes are designated with a “R” in thefourth position of the NBG pacemaker code on the programmer screen.The rate-adaptive modes function identically to the correspondingnon‐rate-adaptive modes, except that the basic rate increases whenphysical activity is detected by the motion sensor.In demand modes (DDDR, DDIR, DVIR, VDDR, VVIR, AATR, VVTR, VDIR,AAIR), it is possible that the atrial and/or ventricular refractory periodcan comprise a major portion of the basic interval at high sensormodulatedrates. This may limit the detection of spontaneous eventsor even exclude their recognition altogether. Further details of thispotential occurrence are provided in Section 7.5.1.CautionRate-Adaptive Pacing—Use rate-adaptive pacing with care inpatients unable to tolerate increased pacing rates.7.1.2 Non-Rate-Adaptive ModesNon-rate-adaptive modes that are programmable with the Estellapacemaker perform similarly to earlier generations of BIOTRONIK pulsegenerators (i.e., Philos II DR and Dromos DR).7.1.3 Mode SwitchingEstella provides Mode Switching to change pacing modes as a result ofatrial tachycardias. Mode Switching is designed to avoid tracking of nonphysiologicatrial rates due to paroxysmal atrial tachycardias (PATs).Mode Switching is only available in atrial tracking modes DDD(R),VDD(R), and DDDR-ADIR.
