Slightly off topic I suppose since it isn’t directly about Jaybo.
This is pretty neat - I ran across it by searching to confirm if a AED can reset a tachycardia. It is a short article, with video that shows what a AED does.
Probably should mark it NSFW as it shows a heart being shocked, stopping, and the natural pacemaker returning it to a normal rhythm
