Examination of excited visible heart

This one was recorded late at night: I could (and should) have been sleeping, but I was in the mood for some fun. I recorded my heartbeat at various points: pulmonic, Erb’s point, tricuspid, mitral, apex, and finally my best guess at aortic (though my heart’s weirdly quiet there…). It was beating somewhat quickly (and very forcefully!) throughout the video, not entirely by accident — aside from the excitement of being on camera, my heart was reacting to some cardiophile daydreams I was having… As per usual, you’ll need to turn your headphones up a bit, but I don’t think the audio’s too bad here otherwise. Enjoy!
