I have downloaded the WFDB toolbox from PhysioNet for MATLAB.
I am trying to read in an ECG file (nsr001.ecg) downloaded from PhysioBank into MATLAB but all my attempts have failed so far! I am using the 'rdsamp' command.
I have downloaded nsr001.ecg (signal) and nsr001.hea (annotation) files. The path where both of the files are located has been added to MATLAB.
What is the correct syntax to use to read the ECG data files from my drive into MATLAB using the WFDB toolbox commands?

First you have to download the rdsign212.m and rdsign212.dll. To read the first N samples of an M-lead ECG (supposing that the data is saved in binary format) you have to use the following command (assuming your data is saved in ECGData.ecg):
ECGSignal = rdsign212('ECGData.ecg',M,1,N)

Add those dat files from MIT BIH into the working directory, Then use import wizard, now you can use the commands like rdssamp..etc
