Hello and thanks in advance.  All of a sudden I started to get a really strong pulse under my left rib cage.  So strong that my husband can feel it and you can see it.  I am a 57 yr old women in good health, but have a heart murmur.  What are your thoughts???  Thanks again,  Barb
Hello! Do not worry. Your situation may be transitory. However, the heartbeat that you refer may be a problem of heart rhythm (Austria). I would recommend you to do some examinations. First ECG (electrocardiogram) to evaluate the heart rhythm; second cardiac ultrasound to see cardiac function. If the situation continues, you need to monitor heart rhythm for 24-hours (Holder rhythm). According to the answers of these examinations, you should receive the adequate therapy. Take care, and thank you for using Chat Doctor for your concern. Please do not hesitate to write again if you have further questions.
