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. Feature and Benefits Large, colour, LCD graphic display visualises up to six ECG signal charts at the same time. Intuitive, basic user interface uses guided procedures to enable the operator to complete the test easily and rapidly. Wireless PC connection using bluetooth technology or, alternatively, via USB cable. Built-in voice recorder to memorise vocal messages during the test (event-marker function) and/or to insert patient details when preparing the test. Incorporated movement sensor to record the motor activity of the patient. Extensive data memorisation, capacity to handle tests lasting from one to seven days.
