The fact that adenosine didn't break the arrhythmia pretty reliably indicates it's not AVNRT or AVRT.

50mg flecainide is pretty low. Has anyone suggested 100mg twice a day? That is the maximum dosage if you weigh less than 154 pounds ... Get a flecainide serum lab test from labcorp

Wow, your situation sounds sounds just like mine ... I just can’t live like this any longer. I’m afraid to exercise and And I’m just waiting for the next episode

. Do you have a reference for the weight recommendations on Flecainide? I had one EP who didn’t seem to think weight was a factor in dosing, so it would help to have a reference—thanks.Quote

To my knowledge, Adenosine will slow, but not terminate, atrial fibrillation. Every episode of AFib that I've ever had starts as SVT and then degrades into AFib within 5-15min.

But even if AVRT/AVNRT are the actual culprits that initiate your afib, the fact that they're able to do so means the afib is there and has to be addressed on its own. Once it's out of the way AVRT/AVNRT should be fairly easy to identify, hopefully in the same procedure.

they completely ignored flutter, which is the most likely form of SVT to accompany afib

don't ... put a lot of importance on that one study as it pertains to you now in 2022

Thanks. I read the thread and all the links, very helpful. I have no doubt about the potential toxicity of flecainide as it caused complete heart block for me. However, I did not see a reference to the weight limitations for dosing in the links, which would be helpful to show to doubting cardiologists.Quote

Weight does make a difference. I had a flecainide overdose and my hr remained in 24 hr for days in the ICU. Flecainide is not a drug one experiments with. Read my links too

keep in mind that class Ic and class III antiarrhythmic medications will slow AP conduction, facilitating blockage of SVT. If the patient has a history of AF or atrial flutter, an AV nodal blocking medication should also be used.”

is very easy for her heart to accelerate to high rates with little exertion. In her case, a high carb diet seems to accentuate this issue. Also, copious Zone 2 training seems to ameliorate this acceleration.

Wow George, this is a dead ringer for for me, thanks for sharing. High carbs (especially at dinner) puts me in the danger zone, and very little exertion while in this zone can trigger an episode. And of course there’s no exertion in the case where I wake up to an episode shortly after falling asleep. My theory is that sudden, outsized blood sugar fluctuations cause an endocrine response, and a particular combination of chemicals that are released will activate errant cardiac pathways. Then we’re off to the races. I’m interested in trying the Freestyle Libre 3 continuous patch to test this blood sugar theory.
I also relate to the benefits of zone 2 training. It has always reduced the frequency of episodes, and unfortunately over the years I’ve been way less consistent with exercise than 20’s + early 30’s.
I have to circle back with my EP to really zero in and quantify the VFib risk in the event I do have Concealed WPW + AFib. In the meantime, I’m back to a diet with zero simple carbs/added sugars and exercising daily with the rowing machine.
