Hi there. I've lurked through this thread now a few times throughout the years but thought I'd finally chime in with my story.
I will only put the condensed version here, you can read the whole thing in my thread on Longecity:
http://www.longecity.org/forum/topic/69669-constant-heart-palpitations-and-adrenaline-like-symptoms/
But, I have been dealing with this since late 2012. My heart does this non-stop, all day long and every day. It always pounds with abnormal force. My pulse is normal, even low, it's just the force of the heart that is way over the line.
I've narrowed it down to it being some kind of neurohormonal issue involving the central nervous system / autonomic nervous system.
In the 3 years I've had this I've found all of THREE things that help:
-Thyroid hormones (since I have hypothyroidism, this just helps me deal with it a bit easier, does nothing for the actual symptoms)
-Valerian root (pretty darn effective considering it's "just a herb", effectiveness-wise it knocks benzo's and other alopathic sedatives out of the park. I tried most -zepam's and -zolam's and they did nothing for me.
-Beta blockers (probably due to their negative inotropic effect, not necessarily acting at the root cause)
For a long time I thought I had adrenaline excess (due to my sweating issues and runny nose) which clonidine helped fix but did nothing for the heart pounding, which seems to be something else.
Food also makes a big difference. I can't touch wheat, it makes the palpitations so much worse and lasts for hours, a sandwhich ruins my entire day. I can eat as much fruit as I want though, so it's not really a blood sugar issue either. Go figure.
