       | I'm a little over 2 months post-op after replacing my bicuspid
       | aortic valve (more common and not as serious as what these four
       | kids have). Growing up, I always enjoyed seeing the EKG printouts
       | and listening to (and watching) the echocardiogram. I was never
       | very good at hearing my murmur through a stethoscope, so the
       | sounds of the echo were super exciting.
       | 
       | My new mechanical valve ticks audibly, and as a musician I was a
       | little worried about how it might affect my sense of rhythm or
       | tempo. Fortunately, I've gotten pretty good at ignoring it,
       | especially when there's lots of other sound, but I can pretty
       | much always hear it.
       | 
       | The sequences shown have BPMs associated with them. I wonder if
       | the product engineers adjusted the EKG results to line up to a
       | particular BPM or just selected portions where the patient's
       | heart rate was pretty steady. I also wonder if there will be any
       | ability to change the BPM on the drum machine. Either way, this
       | is a fun project.

       | Edit: wording

         | I have a bicuspid aortic valve (on top of other stuff that was
         | repaired when I was younger), I could hear my heartbeat until I
         | was 28 when I went on a beta-blocker that decreased the sound
         | levels and is supposed to reduce wear on the valve.
         | 
         | I know I'll need my valve replaced at some point, I hope they
         | gave you a good long term postop prognosis, I know the tech
         | keeps getting better every year.

         | If you don't mind me asking, how old are you and what prompted
         | you to replace it? Just curious how long one can go with the
         | bicuspid valve. While living with it, how did it affect your
         | life?

       | these playable in a browser.
