I didn't have a ton of time to search, but did they mention what kind of software they used? I'm curious what database(s) and schema(ish) techniques were used to hold all of that time series data?

From the video, it looks to me like they used MATLAB.

There are a few open-source databases of physiological signals like the ECG used in the video. One is PhysioBank:
