Get output of Arduino into Matlab

I am new to Arduino. I started working with Arduino before 1 month.

I am getting live ECG signal from human body using Arduino and AD8232 heart rate sensor. Now, I want to detect diseases from Live ECG signal that I am getting. For that I need to use MATLAB Software and apply Wavelet Transform to the output signal that I am getting from Arduino. My question is how can I get my output ECG signal into MATLAB that I am getting in Arduino Software. And for applying Wavelet Transform I need some numbers but right now I just have waveforms not numbers So how can I get numbers from this ECG signal?

Any Guidance will be appreciated. Thank you in advance.

how much data are you looking at in bytes/second?
possible alternatives are serial (text or binary), USB, Ethernet, Wifi, Bluetooth, etc
