15.4. 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

Modulated interference:

For atrial sensitivity setting of 0.2 mV, compliance to the Cenelec standard 45502-2-2 is met

for a maximum test signal amplitude of 8 V for the frequency of 60 MHz. 0.4 mV complies

with the standard for the whole frequency range.

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.
