ECG Raw Data Watch OS

Hello

Do we have access to the ECG raw data on the apple watch?

I was able to access the data using HKElectrocardiogram Class API. "ecgSample" returns all the recorded ECG logs done by the user using the default apple app.

I want to access the data in real-time, do the API supports that? That is, I want to create a custom app in which I direct the user towards recording an ecg signal and then do whatever I want with it.

Please let me know, that would be very helpful!
