The discussion revolves around Rijuven's CardioSleeve, a stethoscope add-on designed to facilitate the acquisition of a basic EKG trace during medical examinations. Participants explore its practicality, weight implications, and personal anecdotes related to similar concepts.
Participants generally express enthusiasm for the CardioSleeve concept, but there is no consensus on its practical implications or comparisons to existing methods.
Some assumptions about the device's effectiveness and user experience remain unaddressed, and the discussion does not resolve the potential limitations of the CardioSleeve in clinical settings.
Medical professionals, educators in STEM fields, and individuals interested in innovative medical devices may find this discussion relevant.

I should have followed up with a device I made to show kids in a science class ten years agBorg said:
I had an oscilloscope and a big lens to throw the output onto a large screen and used a styrofoam cup from Burger King with a Piezo pickup glued inside and then the signal going straight to the O'scope. Put the cup on a volunteer kid's chest and you could see the heartbeat directly on the screen, no electronics or amps needed, just the bare output of the piezo pickup going straightway to the scope and the heartbeat was visible!
