Breakthrough: World's Smallest Pacemaker Is The Size of a Rice Grain

I’d point out this is a temporary pacemaker, not a permanent PPM or ICD. You get these as an inpatient in the hospital when you’re recovering from some pretty intense cardiac procedures. One of the advantages they point out is not having any electrodes to remove in this new device. With temporary transvenous pacemakers, they don’t implant an electrode in the heart, the wire is just chilling there in the bloodstream in your heart.

Not saying it’s not a cool development but it’s going to need a lot of testing and validation before it’s accepted in practice.

Note: I’m not a cardiologist, but I work with them doing EMR stuff and have to know a bit about cardiology.

Pfft. The size of a grain of rice for ants! They'll have to make it at least .... twice as big!

Shrinkflation on rice grains now, apparently.
