CardioLab is now ECG Sweep
Before
The site was called CardioLab, at cardiolab.io. GE sells a cardiac recording system with the same name, so it was time for one of our own.
After
It's ECG Sweep, at ecgsweep.com, named for the trace that sweeps across the paper. Nothing else has changed, and every old cardiolab.io link, embed and shared card still works: it takes you to the same page here.
