Cardioline Walk400h Digital Recorder

The features which distinguish walk400h are:

• 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;
• Single, 5-position joystick to rapidly scroll the device menu;
• Limited size and weight for increased patient comfort;
• Functions with a single AA battery.

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 memorised.
