could someone take a look at these ecgs for accuracy?

I tried posting this in CCU forum but I guess it's slow...so I hope it's okay to ask here.

I'm trying to do some preliminary studying before I have these classes for my new job at the hospital and I have this site from when I was in school. Some of these on the website seem to match okay for what I'm looking at in a book (Lippencott's ecg interpretation) but the 4th group the junctional arrythmias seem to be way off from what's in the book so I'm wondering if the site isn't good.

I did order Dubin's book but it's not in yet. I heard that one is really good for teaching.

When you get the 1st page, just click on the "play" button to bypass signing in. Then there's a "learn" button at the top that will show what the different arrythmias look like when you click on the name.

Thanks for any help.

I've used this site before. The junctional rhythms look right to me.

The junctional looks right on. No P wave

Are you confused about the accelerated junctional rhythms? There you can get a antegrade or retrograde P wave

Ah, thank you yes!

In the book I'm using for reference it is the Accel junctional rhythms that look off. In the book it looks like the QRS complex is inverted and it threw me. Then I guess since I was tired, I started questioning the whole set!

Thank you, I know I have much more reading up on this to really get the differences, I'm hoping the other book helps. Good to know the site is okay.

We used the same program when I oriented and the "junctional tachy" example was a bit confusing at first. As a general rule, a junctional rhythm will still have a narrow QRS since the impulses are originating just above the bundle branches. In the example given here, there is both a junctional rhythm and a bundle branch block, which makes it trickier. The wider QRS clues you into the bundle branch block, and it is still not as wide as a ventricular rhythm.
