Tish, sometimes i get a period of a few days when i frequently notice some kind of brief arrhythmia [ectopics? tachycardia?] which does not feel like afib, and goes away too fast to determine what it is by feeling my pulse. It seems to occur a lot in the early morning. Also sometimes i awaken at night with my heart racing, and it feels very much like the morning whatever-they-are's. I have sleep apnea, and i strongly suspect that the night-time things are related to that.
Both kinds of [ectopics, maybe?] occur at times when i have been slacking off on taking my regular morning and evening supplements of Mg glycinate, K gluconate, taurine, vit D, Vit C, vit E [gamma E with etc.], and COQ10, and also it often happens that i have also been eating something severely nonpaleo. [I am becoming less and less tolerant of wheat.] Returning to paleodiet and resuming 2 doses a day of the above has always abolished them, whatever they are. They have never occurred when i have been eating properly and supplementing religiously. They seem to me to be warnings that unless i straighten out my eating and supplementation i will once more be plagued with afib.
If i am having a particularly annoying spell of them they will vanish as soon as i take 2 grams of taurine and a glass of water with a teaspoon of K gluconate stirred into it. I am not sure, but i think the taurine is the faster acting component of that dose. George too has had some experience with taurine acting very fast to abolish afib, faster than you would think it could possibly have been absorbed.
All this is guesswork, opinions, and hunches, and i have no science at all to back up my guesses about what is happening.
But about the lysine and proline, i think you would be interested in something i stumbled across on one of the rawfood lists some time ago. It concerns what the body actually does with the vit C it uses so much of. Surprise surprise, it has to do with lysine and proline. Here is a link to the thread from the 5th bb where i posted about it, hoping to find somebody who knew something about the subject or was at least interested in it:

Here is the website i got the information from:

And here is a short excerpt from that site:
"In fact, meat not only prevents scurvy because it contains tiny quantities of vitamin C, it prevents it because it bypasses the need for vitamin C.
Vitamin C is required to form collagen in the body, and it does this - despite being described everywhere as an antioxidant - by oxidation. Vitamin C's role in collagen formation is to transfer a hydroxyl group to the amino acids lysine and proline. Meat, however, already contains appreciable quantities of hydroxylysine and hydroxyproline, bypassing some of the requirement for vitamin C. In other words, your vitamin C requirement is dependent upon how much meat you do not eat."
An interesting statement if i ever saw one, and i think it is pertinent to your situation.
