I am a 56 year old female with rheumatoid. I think I may have paracardis. My doctor ran several test but stated that my heart is fine. My heart (sometimes) makes a rubbing sound when beating and I feel a vibration on the left side of my chest. Sometimes I will hear thumping sounds. I have no pain and I exercise at least 3 times a week with no problems.
Thank you for your good curious question pericarditis is not a feature of rheumatoid. You may have ventricular premature beats or paroxysmal atrial fibrillation that's why your physician could not pick up. You may be suffering from anxiety. Get relax and be happy
