I have no info to share about your questions since I don't have any answers. Not an M.D. Plus, we're on parallel but different paths. My BP is low. We have that much in common. I know this only because of a home device. I know my pulse is high. I know this only because I used to donate blood.

I do not have a doctor despite being born with mastocytotis (started out as cutaneous only). It has escalated to GI MCAS (intestinal mast cell activation syndrome). I do know from sending a hair sample to a lab that my magnesium is low. Could be a contributing factor re: my A-fib. Never had any heart trouble that I know of until I took the Pfizer double jab. Then my intestines went berserk (up to nine bouts of diarrhea per day--for weeks)! The MCAS may be the direct result of the vax. And now, with a loss of precious electrolytes, I have heart palpitations. Not as disturbing as in the past. What have I done to calm them down?

I am dedicated to self-care (have to be since I've had so many disgusting experiences with M.D.s--both males and females) and devote one hour per day on research related to vitamins, minerals, herbs, enzymes, amino acids, holistic remedies and more. Learned about the book mentioned above. Learned from another source that interval aerobics can be good for A-fib. Also learned that our nervous system (especially the top of the spine, i.e., neck position) can have a direct impact on heart rhythm. Noted that my A-fib was remarkably worse when reclining on one of our daybeds with pillows behind my head putting my neck in a position that became noticeably uncomfortable after 20 - 30 minutes.

I promise if I learn anything useful or experience some success with a new technique I will share! Goodness is meant to be shared. Just today, I devoted an hour to composing a letter to my favorite cashier at Walmart describing my success in overcoming bilateral chondromalacia patellae, a torn rotator cuff and more! She's facing a TKR (total knee replacement) on August 3rd. I will do whatever I can to give her a chance of avoiding any other joint replacement procedures in the future! Steered her to natural products that gave me remarkable results. Not pertinent here so I won't burden you with the info. Suffice it to say, despite going on 70, acute and cumulative injuries from dance and almost 25 years in a factory, I feel terrific! Now, if I could just get my MCAS and A-fib under control! Oh, I am on ZERO prescriptions. Just two OTC antihistamines.

No answers or suggestions yet. Your situation is similar but different. I've got low BP but high HR. My A-fib is sporadic in terms of my feeling my heart flutter. Call me crazy but I've noticed that certain neck positions exacerbate the A-fib. Have yet to order that book, "Afib Cure." Shame on me. But I'm stretched to the max dealing with my mastocytosis which has escalated to MCAS/GI since the double jab. The chronic diarrhea (now almost under control after a months-long battle) may be the root cause of my A-fib (dramatic loss of electrolytes). I've been low in magnesium and am cautiously trying forms that are purported to be less laxative.

Would like to address the root cause rather than treat symptoms.
