Ryan,
If you have a sympathetic trigger, the caffeine won't help. The PIP beta blocker makes sense. Sounds like you might have mixed triggers.
My motto is "if something isn't working, do something different."
In your shoes, I'd likely detrain, eliminate the caffeine, alcohol and eat as cleanly as possible. Sounds like digestion might be one trigger. My approach is to go to an endpoint and make something happen (or stop happening) then see what I can get away with.

Sympathetic nervous system = adrenergic/adrenaline
Parasympathetic nervous system = vagal/cholinergic
Basically, the sympathetic nervous systems is your heart's "gas pedal". You get excited, or do exercise, and it speeds up. The parasympathetic nervous system is your heart's "brake pedal". You eat a big meal, or sit down in the evening, and it slows down. Either one, or both, can be an AF trigger. Does your AF happen when you're exercising? When sitting down or after eating? Both? These are the patterns you need to establish, as best as possible, to guide your own treatment strategy.

Basically if my heart rate is depressed for too long, it seems get thrown off when it starts speeding up again.

Ryan,
Did your EP rule out SA node malfunction? Although unusual in younger people, it can be responsible for the bradycardia and variability in HR you describe, e.g., from sick sinus syndrome and its variants. It can also be hard to detect. If so, then supplementing with Mg can be counterproductive, due to its calcium channel blocking properties. Your use of beta blocker as PIP to treat some kind of transient tachy phase makes sense to me. And the fact that you react so strongly to it may have diagnostic significance. I would seek out an expert EP with broad knowledge of arrhythmias, and not necessarily follow conventional advice about afib prior to doing so.

Hi All!
I'm new to the forum also. My journey started five years ago with first, an episode of SVT with ectopics and a year or two later, a two and a half hour episode of a-fib. After a couple more years I started having nightly sinus tachycardia/atrial tachycardia episodes (about 3 am), which eventually were more a-fib. They usually go away when I get up.
This past week I had an EP study. I was hoping for some type of re-entrant tachycardia that degraded to a-fib, but it was just a-fib, so more complex to fix. I was told I went into it easily and I had to be shocked three separate times. My doctor didn't do an ablation. I was bummed! They put me on Flecainide and I don't like it at all. I woke up last night short of breath and a regular heart rate of 120 bpm.
I'm appreciative of the support this site offers.
Hi Ryan,
Heart wall thickness is also from high blood pressure. Your numbers are high, especially for your age. Left ventricular hypertrophy is a risk factor for atrial fib. You might be interested to read about methylation defects.
Best to you!
