Need to put this out there. I started using Relvar in March 23. At the time I had no idea this was lined but I stated getting heart palpitations. I went to A@E thinking it was a heart attack. I was having 10-14 ectopic beats per minute. As a test I stopped my inhaler for a few days and my ectopic beats completely stopped. Online it says over 10% of heart beats being ectopic damages the heart! Anyone else experienced this? I did my own ecgs on Apple Watch so it really helped to track it all.
