3rd Degree AV Blocks...HELP! - Page 2Register Today!
- Jan 29, '12 by turnforthenurseRNHow I remember a 3rd degree block: If your P's and QRS' don't agree, you've got yourself a 3rd degree. 3rd degree block is also known as AV-dissociation. The P's are off doing their own thing and the QRS' are off doing their own thing - think of them as "not being married to each other."
Notice how the PR-interval is all of the place. You may also have P's buried in the QRS or in the T waves (as in this example).
...Compared to a Mobitz II (second degree type II) where the PR-interval is consistent but you will have a dropped QRS.

Anyhow, It keeps me sane....
A FAQ would probably be particularly helpful, but that's assuming people would actually read the thing.
- Feb 1, '12 by PneumothoraxP waves will be going at a rate of 60-100 (Sinus)
QRS will be going at a rate of 40-60 (thats their intrinsic rate)
if u have P waves going one speed , and QRS going another..most likely its a 3rd Degree Heart block
