Hello, I was diagnosed with MS in 2009. I am currently taking Avonex. For the past 2 weeks I have been having heart palpitations. Does or Can MS cause palpitations? Could it be a symptom that the MS is getting worse? If not, I am suspecting that I may have low potassium. Can anyone help me with this mystery? Thank You.
I have often wondered that myself. I have had heart palps for years. Have worn Holter monitors and had several echocardiograms. One time I did have low potassium and was kept in hospital overnight to get IV potassium. I get them all the time. They come and go and when they come it is almost constant for several weeks.
I understand what you are experiencing. They can be quite frightening.
There are benign causes but you should still consult your doctor in case you need further testing. Also, it could be a side effect from Avonex.
Hello Sandra. Thank you for your advice. I was thinking it could be a side effect of the Avonex, so I didn't take my meds on that Sunday for that week as my own experiment. I still had palps, so I went and got me some potassium the following Saturday and in two days they went away. I did take my Avonex the next day on Sunday as usual. I see my doc on the 18th, hopefully he has more advice for me. Thanks again.
