I have the EXACT SAME thing as you, man. Down to the details. I seriously could have written your post about myself. And yes, it is scary as shit. Went through all kinds of tests, heart monitors, trips to the ER, ugh. Something I did figure out through all that is that I have insanely low blood pressure. That can cause minor palpitations in and of itself because the lower your blood pressure gets, the harder your heart has to beat to pump blood through it. Something I would do to test this theory (with the consultation of my doctor of course) was to go check my blood pressure at those free monitors inside the pharmacy at random times throughout the day. I was, too, prescribed beta blockers for my irregular heartbeat, and those only made my blood pressure drop dangerously low. This gave me more minor palpitations and made me incredibly dizzy and sick. The only thing that worked was... I started salting my food. I would salt everything, trying to raise my blood pressure. Or drink Gatorade, which has electrolytes. Staying hydrated and properly nourished is extremely helpful. Another thing, I quit the beta blockers and my doctor put me on Flecainide. It's a sodium channel blocker. You might ask your doctor about it, it did actually get rid of my minor palpitations which were occuring every few minutes.
I'm also a very anxious person by nature, so that only made my palpitations worse. Now they've subsided over the past few months and I only get one every week or so. I've gone through about three phases in my life now where these palpitations have become debilitating, but they usually only last for a few months before they subside again. But I know it can't kill me, and I know what to do if I get one. I just lay down flat on my back (no matter where I am) and wait for my heart to slow down. I make sure to carry my phone with me just in case, too. But usually if I start to feel one coming on, I just slow down, breathe slowly and just try to slow down my heart if I can. Keeping hydrated and stress-free also helps a lot.
Hope this helps, sorry for the book but I just know what that hell is like going through that. So yeah, check out your blood pressure, try to raise it if it's low, and ask about the flecainide! PM me if you wanna talk any more
