The Secret Suckiness Of Life After Breast Cancer

Hi @Brenda5, from the position of someone who hasn't had that happen in 3 years, it can improve! I've had the cardioversion (electric shock), the medications and now I am just on betablockers and blood thinners. My cardiologist and I don't fancy ablation (not yet anyway!). My heart rate is steady, not fast and my oncologist (who worried me by taking an eternity reading my pulse last week) says that it's almost not definable as AF or an arrythmia any more!!  I've been lucky that I didn't get the palpitations/flight or fight feelings when in tachycardia, but even so, your pulse racing along can make you feel very uncomfortable. I initially worried that this irregularity was snuff stuff!  I had a regularly irregular heartbeat for decades before bc, it's quite common and not a problem, and I may be actually heading back to that state. You are correct, it's not fun but maybe fixable. Best wishes.
