US/Can healthcare systems still pay a cardiologist a couple of bucks to "finalize" the interpretation whenever they get around to it. It's a bit ironic, someone could have an MI on Friday, get treated and discharged and we're still paying someone on the Monday to read 40 ECGs (note these would have been acutely interpreted by the cardiologist treating the patient, most places have rules against self-referrals so you can't formally interpret anything you order yourself).
