Detection Performance in the Presence of Electromagnetic
Interference in Differential Mode
The Atrial Sensitivity setting of 0.2mV and Ventricular sensitivity 0.3mV (Low Frequency Attenuation
Filter ON) may be more susceptible to EMI (as defined by ISO 14117 clause 4.5.2).
Atrial Sensitivity of 0.3mV (and less sensitive settings) and Ventricular Sensitivity of 0.3mV and less
sensitive settings (Low Frequency Attenuation Filter Off) and 0.4 mV and less sensitive settings (Low
Frequency Attenuation Filter On) comply with the requirements of ISO 14117 clause 4.5.2, which
requires that the implantable pulse generator shall be constructed so that commonly encountered
electromagnetic signals are unlikely to be confused with sensed beats and to change the therapeutic
behavior of the implantable pulse generator.
The common mode rejection ratio for this device for 16.6 Hz, 50 Hz and 60 Hz is higher than a factor of
100.
