I don't know anything about ecg signals, but "help randn" will show you how to generate Gaussian noise.

To add white Gaussian noise:
(assuming you are adding noise for each time step, have your signal in vector 'signal')
rnoise=randn(1,NoTimeSteps);
NoiseAddedData=signal+rnoise;
something like this should work. (FYI, I'm modifying this from my code on Sensor networks, where I have to add white Gaussian noise to simulate noise from the environment for target tracking)
