I was diagnosed with COPD about two years ago and my current FEV1 was 67%. ( I am having my annual check this week). I am also ex forces and have suffered with PTSD for about 25 years. I am on Symbicort (preventer) and Sabutamol ( reliever) inhalers. I really try to avoid using the reliever as it speeds my heart rate up and brings on anxiety attacks and occationally flashbacks. ( I was involved in a large explosion, and struggled to breathe at the time due to the dust) My question is ....is it normal for Sabutomol to speed up the heart and if so would there be a different reliever inhaler I could use instead which wouldn't cause this.
