Hello Always Hope,
After a period of AFib where I did not have 3 steady beats in a row all day, every day..to the point where I felt faint all the time and the Holter monitor malfunctioned. I was put on the maximum dose of a beta blocker, Sotalol. I felt like an old lady but I was only 46 years of age. For almost 2 years I took that drug. The cardiologist told me that my heart could stop at such a high dose and to try to reduce it even by a bit. Try as I might, even cutting out 1/2 a tablet of the 4 I was taking daily, sent my heart into a tailspin.
I read that exercise can reduce arrhythmia and palpitations and I joined a gym. I went every day but Sunday for 35 minutes on the treadmill and then strength training for another half hour. I gradually reduced the dose of beta blocker and my heart remained steady. I was elated! At the end of a month, I was completely off the beta blocker.
My cardiologist said it wouldn't last. I kept going to the gym for 4 months. My heart remained strong and steady...and here I am 24 years later and my heart is fine. No issues whatsoever.
But I am sure half the secret is: since that dark period 24 years ago, I have cut out all stimulants; absolutely no coffee, tea, Coke, decongestants, any ephedrine drugs used in dental freezing or supplements that can be stimulating and alcohol. I have a friend with AFib who prefers to take the beta blocker so that he can enjoy his wine and morning coffee. For me...no thank you! I would rather be off those drugs and their horrible side effects.
Whenever you can, go the 'changes to one's lifestyle' route. Exercise and avoiding stimulants. It worked for me and my extreme AFib. So, it stands to reason that it CAN work for others.
