In this last week, I met with both my Surgeon and my Cardio and the first question I asked was about the THUMPING. They both said the same thing. A certain amount of the thumping sensation is to be expected as the heart adjusts to its new condition following AVR. This may be exacerbated when taking Metoprolol which many of us are given to reduce pulse rate and lower blood pressure. If the thumping is not associated with other symptoms, it should ease over time. On the other hand, if the thumping seems to leave you feeling tired or ill then you should bring it to your Doctor's attention right away. My own is now associated with activity, particularly, after I have been quiet for some time.
Pat, have you also noticed that you can feel your pulse very strongly at your wrist? I used to have some difficulty feeling my own pulse but not any more. I find it very reassuring to have such an indicator that my heart is now getting back to normal.
