This comes from the Murdoch Children's Research Institute in Melbourne Australia. A wrist-worn monitor that finds measurable dfferences in sleep between sufferers and non-sufferers.

Due warning: the report commits all the sins of low-effort news reporting, including dodgy graphics and substitution of the term chronic fatigue for me/cfs. The research itself looks okay.

(I can't find a publication that supports the claims yet but have contacted the researcher to ask)

It's a one minute 40 second video, so even though I don't know what hrv is I can tell you that the video didn't answer your question. It's described as actigraphy.
