Its Friday night and I was bored.. so I went out and bought a Littmann
stethoscope. Listened to myself and found a split S1 that is very
distinct based on the page below. Then I listened to my son and my
wife, and they both have a split S1 but not as distinct as mine. Mine
is more distinct when I exhale.

The only thing we all have in common is hypothyroidism. I have MVP.
I'm sure our cardiologists know we have these sounds but I never knew
what a split S1 sounded like and I don't really know what it means.

Is this common with hypothyroidism or MVP, by any chance?

It is likely that you are hearing the midsystolic click of MVP, which
to the untrained ear can sound like a split S1. The midsystolic click
of MVP is louder when folks exhale and also when they stand.
