 And I've seen some super serious heart scans. I've told the patient, I want you to leave the office and go straight to the ER. Tell them you need an EKG immediately. That doesn't happen very often, but it has happened. With people who felt well, who didn't seem to have any cardiac symptoms whatsoever, they just wanted their heart checked. And here I look at the scan in front of me like, oh my goodness.
