DETECTION CHARACTERISTICS IN THE PRESENCE OF 
ELECTROMAGNETIC FIELDS

Per Clause 27.4 of Standard EN 45502-2-2, detection in the presence of electromagnetic 
fields is characterized as follows:

─

Differential mode:

─

Common mode rejection ratio:

16.6 Hz

50 Hz

60 Hz

Atrial channel

≥ 75 dB

64 dB

62 dB

Ventricular channel

≥ 69 dB

≥ 57 dB

≥ 56 dB

15.5.

PROTECTION AGAINST SHORT-CIRCUITS

The defibrillator can undergo a short-circuit if the anode and cathode are not adequately 
separated.

In this case, the shock is aborted to prevent damaging the defibrillator and a warning will 
indicate that a short circuit (shock impedance < 20 ohms) was detected during the last 
shock.
