I have PA and take B12 losenges and Ia few weeks ago, decided to give my husband one a day for a couple of weeks to top up his B12. He hadn't had a blood test, it was just me thinking it might be a good idea. He had a little bit of tingling in his little finger, but no other real symptoms . We are both 61.
For the last year he has suffered from an irregular heartbeat and atrial fibrillation. His heart rate can go up to 150 a minute during an episode which can last for seconds or hours. He has an Alivecor and uses a Fitbit to keep a check on it as he drives for a living.
Since taking B12 is heart has been steady as a rock - no irregularities, no atrial fibrillation, just a steady, normal heartrate which steadied within a couple of days of taking B12 under the tongue.
I can't find any link to PA or B12 deficiency linked to atrial fibrillation anywhere, although logically, AF is a problem with the nerves of the heart rather than the heart itself, so it would make sense (if only to me!).
There has been no other changes that we can think of that would account for this and we've analysed everything. The only change has been his regular intake of 1000 B12.
His father has PA and has monthly injections, although I'm not sure whether its inherited or not.
My husband is somewhat bemused but very pleased. Does anyone know of any link just so that we are not imagining this.
