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')
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)
