"changed the maximum acceptable PR interval — a heart health metric measured by electrocardiograms — to 300 milliseconds, or 0.3 seconds. A PR interval between 0.12 seconds and 0.2 seconds is considered normal. A PR interval that exceeds 0.2 seconds indicates a first-degree atrioventricular block, which can cause a slower heartbeat or abnormal rhythm.
"The Federal Aviation Administration told PolitiFact [sic] it raised the cutoff for a first degree ventricular block from 200 milliseconds, or 0.2 seconds, to 300 milliseconds, or 0.3 seconds, 💥because the agency’s cardiology consultants provided information indicating that a PR interval under 0.3 seconds isn’t a risk for subtle or sudden incapacitation.💥
Didn't the "consultants" establish "the maximum acceptable PR interval" in the first place?
