      Hello…I noticed an irregular heart rate in June, the evening I started doxycycline for a bullseye rash. I have been on Keytruda now for 13 months, achieving complete response by the 10th month. I was also on Xgeva monthly for a bone mets, now to be every three months; and had covid vaccine in February/March.

      My PCP dismissed it as no concern since I have no other symptoms, but my oncologist ordered an Echo, which showed a good functioning heart. Now I have a cardiology consult next week since I still have daily palpitations. My Oncologist doesn’t think my HR is pembro related but on the Keytruda website, it lists irregular heart beat among a hundred other reactions.

      Does anyone have info on irregular heart rate and pembro or the other meds I’ve been on? Thanks for any insights, as I prepare for my cards visit.

      Cindy

          Hi Cindy,

          Did they check your thyroid function?

          Immunotherapy can sometimes causes thyroiditis (inflammation of your thyroid gland) which can cause palpitations. In that case your TSH will be low and your T4/T3 high.

            Thanks for the idea MelWave, however, thyroid and all labs normal as usual. I’ll have to wait and see what the recommendations are, hopefully do nothing and live with it. Palpitations with no known cause can be common from what I’ve read.

            Best,

            Cindy
