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

67 dB

Ventricular channel

≥ 69 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.
