Does anyone experience a bounding pulse randomly and out of no where that sometimes lasts forever? I’ve had a full cardiac work up basically and everything has always come back fine, and I just have such a hard time accepting that it’s anxiety. 

Also, for those who wear an Apple Watch, what is your usual HRV &amp; what’s your age? If you don’t care to answer. Mine is so low, that it’s just another thing that makes me anxious.
