Source 1 - Screening for cardiac contractile dysfunction using an artificial intelligence–enabled electrocardiogram
Take a look at source 1 (you might have to log in with EID/DUO before you see the full source). You won't have time to read the entire thing, but you can skim the beginning and scroll through the rest of the source to notice characteristics.
Ask yourself:
1. What kind of source is this?
2. What characteristics of the source helped you decide that?
