Jon E. Block et al
Although evidence is scant, the effectiveness of right and left atrial ablations appears to be independent and additive with respect to AF episode reduction.

Today an episode that lasted a few minutes, then stopped. Any idea if this is normal?

Pharmacologic agents are effective in converting atrial fibrillation to sinus rhythm in about 40 percent of treated patients.

And based on my limited knowledge none of the drugs are really targeting the cause of AFIB (If you can find two EP's who agree on that). It's just a lucky coincidence they sort of work for some.

All the antiarrhythmics work by altering aspects of the action potential of cardiac cells. The action potential is just the cycle a muscle cell goes through of charging, firing, and then recharging. For example, some of the drugs widen the refractory period. The refractory period is right after the cell fires and can't fire again until it's fully recharged. So if you widen the refractory period, an errant afib impulse is more likely to encounter heart tissue that doesn't respond, thus breaking the cycle and terminating the arrhythmia.
So what that means is the drug slows your heart cells down by a tiny amount, just milliseconds, and hopefully that's enough to interrupt the reentrant signals of afib and flutter. As you might imagine, those few milliseconds might work for one heart but not another; hence, the hit or miss nature of these drugs.
Note that none of the gobbledygook above has much to do with what causes afib, so you're exactly correct that the drugs don't target the cause of afib.
Now if only we fully understood what the cause of afib actually is....

Dr. John Mandrola
In the short-term, I use temporizing measures to relieve AF symptoms: drugs for rate control, anticoagulants for stroke prevention, and maybe even cardioversion with or without anti-arrhythmic drugs. The key is that these treatments are temporary. We aren’t shocking or medicating an AF patient with the idea that this is the fix; we are doing those things to buy time for risk factor management to work. And it does. I’ve seen it work.

Wolf:
"In a nutshell, the vast majority of the anti-arrhythmic drugs either work to sequester potassium in the cells or otherwise prevent the influx of sodium. Given that the sum of sodium and potassium ions in intracellular fliud is supposed to remain constant, this seems like a basic problem to solve. Eat less sodium and its helper ion calcium and eat more potassium and its helper ion magnesium! "
Funny the guy that has controlled his AF (GeorgeN) eats salt, my holistic doctor tells me to eat more salt. I get AF in the evening while relaxing or sometimes by putting pressure on my upper stomach or the back area, but not in the daytime. Do you think my salt/potassium levels are more in synch in the daytime. I know people that put a lot of salt on their foods and no AF.
I wonder what Dr. Natalie believes is the cause of AF in some of us.

...electrical remodelling in AF can be reversed in some patients if SR is maintained from an early stage, suggesting that prompt recognition and management of AF is critical.
