Hi, I’m thinking of taking Mounjaro after a friend’s amazing results. However, the Boots online questionnaire says up to one in 10 users have raised heart rates. This has alarmed me as I had multiple episodes of atrial fibrillation last year after getting Covid with many visits to A&E. I ended up having an ablation which has so far been successful but the cardiologist told me to stop cold water swimming, reduce caffeine intake and give up alcohol. All of which I have done (sigh). Has anyone on here with a similar medical history used Mounjaro successfully? Thanks in advance.
