[|Human|] Hi There I had valve replacement surgery 2 years ago. No problems since ,and no heart meds. Recently, when lifting heavy objects my heart beats fast and I begin to lose my breath. What could be happening? I am a 59 year old female in relatively good shape I m 5 foot 4 inches and weigh 115lbs. I dp yoga and light weight training. Occasionally cardio
[|AI|]  When you say post replacement you are not on any medical treat, you must have a bio prosthetic valve replacement.  In spite of such a regular lifestyle if you have a symptom of breathlessness and palpation, I would suggest you to get an ECG for heart rhythm and a 2D echocardiography for the status of the valve.  The above episode may have no relevant medical cause, but it's safer to rule any possibility :) Regards
