Table 11: Magnet response after reaching ERI
a) The pacing rate decreases by 11% in the pacing modes DDD(R), DDT(R), DDT(R)/A,
DDT(R)/V, DOO(R), VDD(R), VDI(R), VDT(R), VVI(R), VVT(R), AAI(R), AAT(R), and
AOO(R). In the pacing modes DDI(R), DDI/T(R), DVI(R), and DVT(R) only the VA delay is
extended by 11% . This reduces the pacing rate by 4.5-11% , depending on the selected
AV delay.
In dual-chamber modes, the pacemaker switches to single-chamber
pacing when it reaches replacement indication. This replacement mode
varies according to the programmed pacing mode and is shown on the
programmer.
The replacement indication is also indicated by the programmer when
interrogating the pacemaker; it can then be printed out with the data.
The battery status can also be tested using analog telemetry.
Nevertheless, the reference for the replacement indication is always the
basic rate.
Deactivating Functions at ERI
The following functions are deactivated when ERI has been reached:
• Night program
• Rate adaptation
• Atrial overdrive pacing
• Rate hysteresis
• Rate fading
• Lead check
• Active capture control (ACC)
• AV hysteresis
• PMT protection
• Statistics are not continued
