I have an ablation scheduled the day before Thanksgiving. My first diagnosed AFIB event was December 2023. I ended up in the ICU for a week. I had a pulse yo-yoing up to 190 BPM and a BP of 170/130. My TSH was .015 which is what they said was the cause of the AFIB. I had been taking T3 on my own to shed the last bit of fat for a competition. My normal TSH levels for a decade were between 3.0 and 3.4. Obviously adding in T3 on my own suppressed my natural thyroid production and caused the TSH collapse. Was prescribed metoprolol, losartan and hydrochlorothiazide (hate all 3 especially the metoprolol as it made me lethargic and depressed). Over the next 2 years and 4 months had maybe 2-3 "possible" AFIB notifications on Kardiacare which went away within an hour or two. Those occurred on vacations where I tend not to sleep well, eat too much rich food and indulge in alcohol.
Cut to June of this year. My cardiologist had taken me off the metoprolol as I had no AFIB notifications for 12 months. I had a kickboxing competition coming up and my dumbass got reckless and used a prohormone called Superdrol (not classified as a steroid but it provides intense strength gains over a short period and is obviously not good for the heart. Even many bodybuilders avoid it because it can produce major side effects). Two weeks after starting it, I went into AFIB and was cardioverted. Doc also sent me for a sleep study and it showed sleep apnea (which certainly could have caused my AFIB too) with 28 interruptions per hour and I have had a CPAP for the last 2 months. Doc put me back on metoprolol and added amlodipine.
Saw an EP. Before I could explain my history, she suggested an ablation. I explained that my 2 major cases of AFIB were possibly self-induced by my stupidity of taking a large dose of T3 and effectively an intense prohormone. She still said I should get an ablation. Other than AFIB, my health markers for liver, kidneys, cholesterol, etc. are all excellent. Ejection fraction is 57%. I take very good care of myself. I'm 6' 6" 250ish lbs. and my bodyfat ranges between 9-11% depending on winter or summer. I lift weights six days a week and do 60-90 minutes of cardio a day. I've never smoked a cigarette. I drink maybe 4-5 times a year and eat very healthy. I even cut my one vice (diet sodas) down to 2 a day instead of 6 and have transitioned to Olipop from Diet Sundrop.
The EP seems to be hyper-focused on an ablation and dismisses my concerns over the procedure not working or causing complications. I don't intend to ever put a steroid or prohormone into my body again and have addressed my sleep apnea. The EP says by doing the ablation now it could be a preventative measure. Also, I have hit my insurance deductible and out of pocket for the year so the ablation should be almost totally covered. If I put it off, it would certainly come with a higher cost.
I asked both my GP and Cardiologist their opinions. They defer to the EP but do express a bit of hesitation knowing the fact of the highly likely possibility that my ingestion of substances could have caused my AFIB. They both stated that since I have had two bad occurrences of AFIB, the likelihood of AFIB in the future does increase. But my cardiologist pointed out that it was almost two and a half years between events. They basically gave me a 50/50 answer. I do have a resting heart rate of 80-85 BPM even on metoprolol so maybe this will help with my tachycardia (can it?).
Any advice or opinions would be appreciated especially from anyone else who may have used something like T3, clenbuterol, prohormones or steroids.
