I was both happy but not surprised to see autism pop up in relation to this. I was recently diagnosed and a key part of it is over-sensitivity and misinterpretation of bodily sensations. I've always been 'overly' aware of my heartbeat and it has caused me distress, but since wearing a Fitbit 24/7 and being able to see that, no, it's not off the scale, things have improved. I guess that's a sort of very lightweight, passive version of what's going on in this research. Beta blockers have also proven to be very efficacious as a way of breaking out of cycles of worry/response.
