15.3. RESPONSE IN THE PRESENCE OF INTERFERENCE
If the defibrillator senses electrical noise at a frequency above 16 Hz, it
switches to an asynchronous mode at the basic rate. The programmed
mode is restored as soon as the noise is no longer detected.
Ventricular pacing is also inhibited by ventricular noise. It can be
restored by setting the parameter V pacing on noise to Yes.
15.4. DETECTION CHARACTERISTICS IN THE
PRESENCE OF ELECTROMAGNETIC FIELDS
