I need to be able to open, display and proccess an ECG in Labview. I have attached txt file with the ECG raw data in HEX format
Below are instructions that can be used to draw the actual ECG image from the ECG raw data.
1) The ECG measurement compressed data is received in the external system Web service request and returns all the signal points in a format ready for display.
2) The ECG signal for display is built of 1 KHz samples per second. Each sample (point) value is given in uV units. For example a point with value 1000 = 1 mV (in the y-axis).
3) The ECG signal for display graph points are calibrated to appear in the center of a +-5mv graph.
4) The signal is provided in HEX string. One point is represented by 4 ASCII characters representing 4 Hex values for a 2 bytes signed-integer. The 2 bytes are listed in LSB to MSB order from left to right.
Example: the string AB34CDE5 represents 2 points
First point: AB34
Second point: CDE5
You can you the information above and the attached txt file for testing.
