LabVIEW
Ask how to open some files
I already poste a link to these files long ago, If the files are public, they should never be attached again, zipped or not.
This was an interesting problem and I was happy to play around, especially since I have a personal ECG monitor where I could not yet correctly reverse engineer the binary format for my own analysis in LabVIEW 😞
I am sure your use is educational and not commercial. It is an interesting project to analyze and compare all these pathological ecg sample traces.
I did not even look at the other three file type (not *.dat files), because they are very small. They might just contain metadata (e.g. time-base, recording date, formatting, etc.). The *.dat file contains the recording and is probably all you really need.
Maybe somebody could look at the MATLAB tools I linked earlier to see what they do. I don't "do" text programming and did not even bother.
Still, I recommend to start with the basic LabVIEW tutorial and especially learn about the various numeric representations. In this particular case, reverse engineering was relatively easy. If we just graph the raw U8 data, there is a periodicity of three, indicating 24bit data. (3bytes/point) After that there are only two possibilities for byte order (big vs little endian) and two possibilities (signed vs. unsigned integer). Harder was figuring out the wrapping, and there might be other ways to unwrap, but my solution seems to work fine.
