Albuterol is supposed to be more specific to the B2 receptors and less to the B1. In my experience that hasn't been true.
Remembering the saying "B2, you have 2 lungs. B1, you have 1 heart". Beta-sympathomimetics affect the heart and lungs in opposite ways. They dilate the bronchials to help with breathing, but constrict blood vessels and increase the heart rate.
Have you tried clenbuterol? My albuterol inhaler (I know you're doing it orally) puts my pulse over 100 and makes me dizzy. I can tolerate clen a lot better.
As you would imagine, cut back on the dose until she gets a tolerance, or wait for a few days for one to develop at the current dose. If you have access to blood pressure monitoring, do it.
