Technical Parameters

Magnet Mode

Parameter Rate
Magnet pacing mode Fixed rate pacing in programmed mode.
Magnet rate, battery status "Good" 100 min-1 (600 ms)
Magnet rate, battery status "Ageing" 95 min-1 (630 ms)
Magnet rate, battery status "Replace PM" 86 min-1 (700 ms)

Warning: In magnet mode the pacemaker operates in an asynchronous pacing mode. If the intrinsic rate is higher than the magnet rate, this may induce ventricular tachycardia or ventricular fibrillation.

is present. If interference continues, the eventual pacing
rate is either the sensor-indicated rate or the lower rate,
whichever is the higher.
