For the purposes of this document the following definitions apply:

Bimodal compression

The use of low pass filtering and sample decimation outside of a protected zone containing the QRS complex, with no decimation or filtering within the protected zone, is called bimodal compression, and is indicated by a flag in section 6 (please see clause 5.9.2 byte 6 of the SCP standard document).

Fiducial
