I recent had an angiogram and because you have to have a pulse rate of 60 bpm or less! (whereas mine is typically in the 80-90s and normal can be between anything from 60-100) - was given beta blockers to get my pulse down to the required rate. Now, I really don't know if I imagined it, but with a reduction in my heart rate, I felt I could breathe just a little bit easier. My Specialist said that this is possible and that the medical fraternity is revisiting this subject. BTW I have never had any issues that I know of with my heart. Stay well. Martin
