thank you Irene,
it took me a while to answer but the change to levalbuterol did help. It is through the inhaler. I noticed right away the palpitations dicreased in frequency and the stress test which I had two weeks ago did not show any changes. Next week I am going to get hooked up to the monitor, I think they use a patch now, just to eliminate other heart concerns. The issues just multiply with time. Now I have a flare-up (the first one since I started MAC meds) and the cough is horrible (second day on levofloxacin, extra airway clearance, nebulizing 7%. I pray it helps.
