When the Magnet Response is programmed to Inhibit Therapy, application of
the magnet will inhibit and/or divert charging for a shock, divert a shock that is
about to be delivered, or inhibit and/or divert further ATP therapy.
When Magnet Response is programmed to Inhibit Therapy, initiation of
tachyarrhythmia therapy and arrhythmia induction is inhibited any time the
magnet is properly positioned over the pulse generator. The tachyarrhythmia
detection process continues, but therapy or induction cannot be triggered.
When a magnet is placed over the pulse generator, the follo wing will occur:
• If the Tachy mode is Monitor + Therapy or Off when the magnet is applied,
the Tachy mode changes temporarily to Monitor Only mode and will
remain in Monitor Only mode as long as the magnet is applied. Three
seconds after the magnet is removed, the mode will return to the previously
programmed m o de .
• If the pulse generator is charging to deliver shock therapy when the magnet
is applied, the charging continues but is then terminated within one to two
seconds of magnet application, and the charge is diverted. (This delay
occurs in case the magnet is inadvertently passed over the device when
therapy inhibition is not desired.) The pulse generator remains in temporary
Monitor Only mode while the magnet is applied. No further therapy is
initiated until the magnet is removed; however, detection will continue.
• If charging is complete or co mpletes within the 1–2 se cond delay period,
holding the magnet over the pulse generator for more than two seconds
will divert the shock. (If the magnet is removed during the delay period,
the shock could still be delivered.) Shocks will not be delivered with the
magnet in place.
• If the pulse generator is initiating fibrillation in du ction o r ATP p ulses, it
terminates the delivery after one to two seconds of magnet application. No
further induction or ATP pulse sequences are initiated until the magnet
is remove d.
• If the Tachy Mode is Monitor Only or Off, magnet application will produce a
constant tone to indicate that the device is in a non-therapy mode.
• If the Tachy Mode is Monitor + Therapy or the pulse generator is in
Electrocautery Protection Mode, magnet application will cause the pulse
generator to beep once per second to indicate that the device is in a
therapy m ode.
