A record for medical students to hear normal vs “pathological” hearts. Lots of super awesome science speak about hearts & their defects. Lots of rhythmic hearts beating in a muffled stutter. If you enjoyed that dog heart sounds record I posted, clearly this is for you (and vice versa). A friend, the proprietor of the exceptionally rad music/tech blog Zed Equals Zee, scored this for me. She clearly knows my interests well.
