I wish they offered some more detail on how important/life-threatening this is. Are we talking monitoring as in "detect signs of impending/occurring cardiac event and notify emergency services"? Or is this monitoring in a longitudinal sense, assisting physicians to look at trends in their patients? If it is the later case, is data stored on the device until it's uploaded, or is it simply lost if the connection fails?

Still, not really forgivable to be 100% AWS, but it's a very different story if this is primarily a recording device vs. a monitoring device.
