15.2. MAGNET MODE
When the magnet is applied:
─ antiarrhythmia functions are inhibited (detection of rhythm
disturbances, charging, and therapy),
─ hysteresis, VV delay and AVD paced/sensed offset are set to 0,
─ pacing amplitude is set to 6 V,
─ pulse width is set to maximum,
─ pacing rate is set to the magnet rate,
─ the following functions are disabled: ventricular arrhythmia
prevention, Mode Switch, Anti-PMT, Smoothing, Rate Response.
When the magnet is removed:
─ the sensor rate is forced to the basic rate,
─ arrhythmia detection algorithms and sequential therapies are
reinitialized,
─ therapies start with the least aggressive program for each area.
The other parameters remain at their programmed value, including the
ventricular paced chamber parameter.
NOTE: The magnet is inactive during telemetry.
The magnet rate values are as follow:
