Apart from having breast cancer, I'm quite fit and healthy. 41yrs old and just finished 6 cycles of chemo. My resting heart rate used to be between 60-70 and I've realised it is now 80-90 sometimes a bit more. I don't feel it racing or anything, no palpitations, pain or anything but I'm a bit concerned as to why it is so high. I was just wondering if it is likely that the chemo has caused this? And also if this does happen due to chemo, does it usually go back to normal?
Thanks for your help with this.
