I am responding to Mayo Clinic Connect members. I have had pulsatile tinnitus for more than four years . . . a constant beating of my heart in my left ear. During this time, I have heard many sounds described that others are hearing. My tinnitus sounds like a heart beating. I guess I am fortunate that it has never stopped. I have been to an internist, two cardiologists, two otolaryngologists. One of the otolaryngologists did a scan or two but I was never able to speak to him after them or get any results. The nurse practitioner called and said that I am “fine.” Even though I did not have high blood pressure, the first cardiologist prescribed Metoprolol and Losartan and I have been on those two drugs for years and still have the unchanging, constant heartbeat. Good luck to all of you with similar problems. I hope you can find a physician to treat you. @kittyrushing
