FAA increases upper limit of ECG normal PR interval by 50%, and increases the total normal range by almost double.

This item 58 (ECG) along with item 36 (heart) was revised on October 26, 2022 in the FAA guide for AMEs. The normal PR interval range was previously .12 to .20 seconds (200 milliseconds). On October 26, 2022 the upper limit was increased to .3 (300 ms) or increased by 50%.

The most recent ALPA FastRead told us this was misinformation and that they confirmed with the FAA this change was made in 2018 and provided a link to an article. The article was published in 2018 but there is no details given except for a video. Not sure when the video was made, but it was posted only 5 months ago. Or 2 months before the official revision in the FAA’s AME guide. The video could not have been created much earlier as the 2021 guide and up until May 25, 2022 the AME guide still had the upper limit listed as less than .21 https://www.faa.gov/sites/faa.gov/fi.../avs/guide.pdf. Item 58 page 244.

Not sure why the FAA would need to change the limit or even think it matters what year the change was made or why ALPA would feel a need to cover for them. The .2 or 200ms upper limit is considered standard for normal variants amongst medical universities and institutions.

Maybe the FAA has the same data as Harvard University…

“a prolonged PR interval is most commonly seen in generally healthy, middle-aged to older adults and has been thought to reflect normal age-related changes. But previous investigations of the impact of PR prolongation were limited to younger, healthy participants, such as members of the military.” “A PR interval of less than 200 milliseconds is considered normal, and participants whose interval was longer than 200 milliseconds had twice the overall risk of developing atrial fibrillation, three times the risk of needing a pacemaker, and almost one and a half times the risk of early death. Further prolongation of the PR interval led to even greater risk.”

I’m with you, my man. Birds definitely aren’t real.

We all know why, it’ll just get taken down from this board if discussed.

The Earth is indeed flat. Also, 9/11 was an inside job

So youre saying the FAA did not change the ECG requirements? Their guide for AMEs is Russian disinformation and made up of fairy dust? ALPA sent out email for something doesn’t exist? Got it. ALPA must be staffed by a bunch of conspiracy theorists I guess.

What are you rambling about? Did you read the article?

Thedude86

I did. Did you? Can you explain why the FAA decided to change the requirements?

CBreezy

The article did a very good job of explaining it using quotes from cardiologists from very reputable institutions. Try reading it again

Yes. And the updates are from 5 months ago . If you can provide the actual original article from 2018 id be happy to take a look. The official FAA guide in 2021 and as of May 25, 2022 as provided, still has less than .21 as the upper limit. Per the FAA’s own revisions it was not changed to .3 until October of 2022. I don’t know how you would view that as a conspiracy when its in their own publications. If you can show me where it was changed to .3 in 2018 I’d love to see.

Just google “normal ecg pr intervals”…. Pretty much every single link and/or article on the first page ALL says up to .2 or less than .21 is the normal range. I see absolutely ZERO about .3. Looks like the FAA is the outlier on saying normal is up to .3. I honestly don’t know why they would feel a need to suggest something that no other medical institution reports.
