ecg signal in matlab

I have downloaded an ecg signal from MIH physionet org, and it has .dat format. I loaded into matlab using the following code:

x1= load ('16265.dat');

However, I'm getting this error:

Error using load Unknown text on line number 1 of ASCII file C:\Users\student\.wfdb-swig-matlab\16265.dat "ÿ".

Any thoughts ?

Thanks in advance

Those are not simply ascii files you can use load() with. They are binary files.

Please read the following to learn how to read them in MATLAB
