I saw my Cardiologist earlier this year. He had a new resident training who had no idea how to use the echocardiogram. Heaven help us!
Heck, Randy Mantooth knew how to run one back in the 70’s!
I have a Kardia device that seems to provide good electro heart data for 30 seconds at a time.
Nearly as good as what I see during brief annual visits, but always accessible [and it logs data for “sharing”].
This is true in engineering too. I’ve seen brand new EEs who have never used an oscilloscope. What are they doing in school?
