I am familiar with the full body jerks that wake one up during sleep.
I don't currently get that symptom right now and have rarely had it.
I get a heart palpating, throbbing vibration that feels like it is an adrenaline surge (I don't feel any anxiety though). It lasts long enough to pulled out of the nap I was trying to take by making my hands throb and chest kind of vibrate). It happens specifically while I am drifting off to sleep (about
90% of the time).
However, after that happens I usually am able to fall asleep without it happening again. Occasionally it can happen multiple times throughout the nap but that is rare.
I would also guess it may have something to do with POTS?? I don't know...
