Parameters
ratio, which may enhance sensing performance and may reduce oversensing T waves. Turning the Low
Frequency Attenuation filter On or Off changes the device’s sensing performance and may impact the
reported R wave amplitude. For more information on how turning the Low Frequency Attenuation
filter On or Off affects the sensing ability of the device, refer to the device manual.
For best results, the Low Frequency Attenuation setting on the PSA should match that of the selected
device.
The default setting for the Low Frequency Attenuation filter is On for all tachycardia devices except for
CRT-D devices. The default can be changed by selecting the Save as Default button on the Advanced
Settings screen.
