I can hear my new heartbeat for the first time today, it's kind of weird. I have a mechanical valve and it sounds like someone is bouncing a basketball down the street. I had surgery May 30th and last night in bed was the first time I noticed it and now today I can really hear it. I lost four pounds overnight so I wonder if that is why. It doesn't sound like I thought it would, which is a good thing I guess. I thought it would be a constant tick that would drive me crazy, but so far it's o.k., just strange, in a good way.
