Increased heart rate on chemotherapy

Hi Anxiousjan  I had exactly the same thing. I had 4 EC then 4 Paclitaxol and had it with both drugs. I’m now 2 weeks post last chemo and my HR still increases with no reason and no warning but I was always assured it was quite normal! I’m hoping as I slowly get my fitness back my HR will reduce and go back to something more reasonable! So basically don’t worry, it’s quite common and perfectly normal! Good luck with the rest of your treatment! X

Yes I did during chemo and got breathless - had a scan - put down to bring just a side effect. Post chemo it’s also remained a bit higher too 

Even now months after chemo, heart pumps so hard I can hear it in my ears, but not on a regular basis. Like you, had lol the tests. Nothing wrong. Just a side effect. Sending best wishes with the Red Devil! X

I had this. For me, it was heart damage caused by the EC. I started with Atrial Fibrillation - where the rate just wouldn't stay still, jumped up/ went down - which i actually think were the steroids. That got worse after the EC, because you need more steroids with Docataxel.

I felt terrible, my heart rate was bonkers high - 152 one morning. The oncologist was quite dismissive. She did a MUGA scan which showed a drop in heart function, but was still technically good enough for her.  Had another chemo and ended up in the hospital.  Saw a cardiologist, who was clear that there was heart damage and inflammation. I had to stop the chemo.SInce then have had a few holter scans, MUGA's to track the damage and started on a beta-blocker.

The one positive is that since this was all caused by chemo it did calm down and get better when i had a 4 month break for surgery (I ended up having several). Now I'm on Kadcyla chemo and the Herceptin in that is making heart stuff flare up again.

Oh mu gosh! Hiw scary! The poison has so much to answer for. Really hope you get through the rest of the treatment quickly and either little/no more issues! Best wishes xxx

Excuse typos, doing this while on dog walk on phone xx

My heart rate is always high too when I have it checked at hospital. Every time I end up having ECG and chest x-ray which shows nothing

I have had ECG, echocardiogram, blood tests, chest x ray and CT scan all of which showed nothing at all. I came off EC at the end of February and have been on paclitaxel weekly since then. I think I have had less problem with the heart rate on this. It still speeds  up more than I would like when I move around but it seems to settle to a more acceptable resting heart rate faster than it was doing. Occasionally the resting rate goes back to my pre chemo 60 beats a minute. Mostly it is around 70 whereas it was frequently 80 or more on EC.. The taxel however has landed me with peripheral neuropathy in my fingers and toes. Hoping the nerve endings will recover in due course. You just can't win with chemo! Still it is my last one next week. Hurray!

I've had high heart rate and breathlessness during chemo. Every time I end up at day unit on red card emergency they worry and I have a chest x-ray which is always clear. I'm not too worried as it is constant
