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.

Certified medical laboratory scientist here: reckon we still do this because it’s fast, free, requires no technology, and can give you some decent insight into what’s going on. Of course, you’re going to want chemistry and microscopy to confirm anything, but color can certainly steer you towards a pathology. Even the fancy analyzers with automated dipstick chemistry and computerized microscopy report color and clarity.

Also if your pee is any darker than straw colored, drink some water. I’ve seen so much nasty piss come through the lab. Apparently a ton of people aren’t drinking enough water.
