Which treatment you're in is relatively easily detectable, so unfortunately that wouldn't work.
I like the approach though, it would be a reasonable control condition (assuming that the 60bpm is a core part of the effect).
you would blind the participants to the effect you are looking to measure. If they don’t know what to expect or what conditions there are, they can still get a placebo effect from random patterns.

Maybe. Generally you'd do a manipulation check at the end to ensure that people couldn't identify what condition they were in.
Additionally, that's single blind rather than double blind.
The researchers can be blinded by not experiencing the intervention and handing out identical looking devices. You’re right that you would need a manipulation check at the end but this experiment is totally design-able properly.
