Hi all you experienced people here. I am 25 days post op from my AVR. I have been doing pretty well except now for the last couple of days. I have been on Metoprolol 25mg twice a day since surgery. At first the coughing I had I thought was related to the surgery. Now I have bronchial spasms all the time which make me want to cough. I can't talk (which I of course love to do) or sleep. The bronchial spasms are involuntary. I called my heart surgeons office today and they told me to stop taking and keep a watch on my blood pressure which has been great. I noticed after not taking the Metroprolol for over 16 hours the coughing and bronchial spasms went mostly away but I have been having a erratic heart beat from 96 to 166. (Called the dr. but they haven't called me back yet). I went ahead and took 1/2 (12.5 mg of the Metoprolol and here comes the bronchial spasms and wanting to cough again) in the meantime to get my heart rate back to not being so erratic. Have any of you experienced any of this and what did you finally end up doing to make it work? Thanks for any of your wise comments. They have helped me through this whole AVR and being on the other side. Kim
