Title: The history of the pacemaker
Post by: John Fruits on December 28, 2018, 08:33:50 pm
This may be of interest to some people here, I just ran across it on a web page for 100 awesome facts. 
It is a very looooong web page and the history goes way back, as far back as Mr. Peabody's WayBack Machine.
Along the way it covers the invention of the ECG (or EKG) machine.
