Ask HN: Looking for a past post about heart cell excitation

Hey!

I’m looking for a recent post (around 3-6 months old) in which grid animations are shown to demonstrate the process of heart muscle cell activation, and on a later stage, how a clump of dead cells can provoke a “vortex” and electrical reanimation is needed. I tried searching for it with Algolia but it’s not showing up.

Thank you in advance.

That was it. It was in fact only 3 weeks ago, not 3-6 months. Time flies in reverse for me. Thank you
