I saw this tech presented at Compute Midwest (KC) a week ago and it was mind-blowing. It can do amazing things, including serving as a true EKG. The article seems to focus more on the blood speed measurement, perhaps because that's one of the more novel abilities of the device, but to answer the core of your question - it can already relay EKG-quality statistics about a potential heart condition. Another exciting capability (IMO) was that they've also experimented using the sensor to emit specifically-tuned electrical pulses from the sensor into your skin, basically triggering a haptic response. So a haptic suit with VR goggles is now in the realm of possibility.
