Muscle Filter/AC Filter

Muscle Filter Frequency

9-6
System Setup: 12 Lead Mode
[yes]: In 6_F1 reports, the first 6 leads represent the first half of the 10-
second signal acquisition period, while the second set of 6 leads
represent the 2nd half of the acquisition period.
no: The second set of 6 leads also represents the first half of the
acquisition period.
The same is true for the report format 3_F1.

4x2.5R3, 6_F2, H2 become 6_F1_R, 3_F1_R, 4x2.5R3_R, 6_F2_R,
H2_R.

Filters may suppress diagnostically relevant portions of the signal,
because they limit the transmission range. Therefore, only enable
filters if necessary.
Cut-off frequency of the muscle filter: [40 Hz], 20 Hz.
The frequency range is indicated in the lower margin of the recording
strip.
„
0.08 – 40 Hz (40-Hz muscle filter enabled)
