I just wanted to add, that back in 2011 when I had radiation at first diagnosis I had a history of heart palpitations, but it was rare. 6 months after treatment I started to get them relentlessly, til 1 day I was alone and passed out, ended up in hospital with possible heart muscle damage as it was equivalent to running a marathon they said. It had been going for 10hrs..big mistake.
So I ended up having a heart ablation done, and it cured it! they just cauterize the nerve pathways across the heart, so its not the function of the heart thats the problem. 6yrs on and am great.
I also wanted to say however while on FEC in 2015 my heart was constantly labouring and beating fast, all over the place...so it affected it greatly! It has settled down now..but I cannot exercise like an athlete for many reasons and chemo is a major culprit...
