The Walk400h is able to acquire and memorize from 3 to 12 ECG channels, compatible with the holter reader software CARDIOLINE®, for details of which see the relevant documentation.
The beat-beat acquisition of each ECG channel is performed at a minimum frequency of 250 samples per second per channel. For special analytic tests a higher sampling frequency may be chosen. All the ECG channels are recorded without interrupting the beat-beat acquisition of the signal and without any sort of signal compression.
The recorder contains a flash memory of one GB thanks to which holter charts lasting a total of one week can be memorized.
