EKG Z-axis?

[hawkwing]

I read a segment on this in garcias book. Is anyone using this? It seems like an unnecessary step to determine it exact or am I missing something?

I read that part too and have never seen it used, even on inpatient cards

Thanks! I suspected as much after asking one of our cardiologists and she basicly had never even heard of calculating z-axis.
Do you have any suggestions on what to read after garcias 12-lead and arrhythmia books? It already feels like im lightyears ahead of my class who i struggling with Dubin and Thaler but one always want to get better.

Mattu's ECGs for the Emergency Physician has 200 random one's that are all great examples. I agree with you about being ahead--having the ability to pick up the subtleties can make you look like a rockstar

Also check out emrap tv (google it) for some great 5-10 min lectures

Thanks! I just got the books and theyre great exercise, ill probably need it as I will be doing my first rotation in the ER on friday. 🙂

Dubin's Rapid Interpretation makes me want to slam my head into the wall.

Seriously I can't believe they actually encourage us to read this ****. It's written for third graders

Anyone have any better suggestions for an EKG book? And does anyone want a copy of Dubin's? I just so happen to have one for sale

He also has an arrhythmia book thats a great read after you finished with the first one. And no, I definetely dont want any Dubin under my roof. 🙂

Im having some moore "trouble" after reading the first Mattu book for a while. According to Garcia V1 - V3 ST-depression can only be reciprocal to posterior STEMI. In Mattus book in ECG 37 he says that V1-V3 depression are typical reciprocal changes in a inferior wall STEMI.

How can they be when they are in different planes to I, II and AvF?
If it is correct how can I then differentiate between a pure inferior STEMI and an inferoposterior STEMI?

Im confused. Any thoughts?

Not sure exactly since I don't have either of the books with me right now, but when I think posterior, I look for R-wave progression.

For me, an important algorhythm that gets me out of a lot of jams is all about poor R-wave progression in the precordial leads
1) LVH
2) LBBB
3) Anterior wall MI

When I think about accelerated R wave progression, I think about the opposite of all of the above, plus WPW type A:
1) RVH
2) RBBB
3) Posterior MI
4) WPW type A

For all practical effect, the main point is whether they're having a STEMI or not so they can be cathed.
