... rapid heart beat (about once every couple of months and the rate would be about 130 beats per min.). But in the past 6 to 12 months it has escalated to once a month at 160 per min. and last 24 to 36 hours. My doctor has switched me to Spiriva and the same result. Now I am on Flovent and same problem. I take a beta blocker which slows the beat to about 130 but it still has a duration of 24 to 36 hours. Any ideas as to how to combat this rapid heart beat? no other inhaler works very well
