37 Year Old Male–CC: Chest Pain, Part II
This is part II to “37 year old male–CC: Chest Pain“. You may wish to review the case. So, while many of our cases are straightforward, this one is not. But hey, our patients don’t read the textbooks! First, let’s review the chief complaint: Our 37 year old male had “chest tightness”, but complained of lethargy […]

The 12 Rhythms of Christmas: High-Grade AV-Block
Thanks for reading! Correct, in complete AV-block, there shouldn't be any P-waves that conduct (except for the phenomenon of "supernormal conduction," which is rare enough that we won't worry about it). In a standard second degree AV-block, whether Mobitz type I or type II, there will be occasional P-waves that don't conduct. What differentiates "high…

The 12 Rhythms of Christmas: High-Grade AV-Block
So, if there are some P waves that conduct with some that don't, then its a high grade av block.. In CHB, there is no p wave conduction. Right? Nice article.

Does T wave changes in reciprocal leads always positive?

Cardiac Axis Determination – Part 5
Thank you very much for this! I'm in paramedic school and the paramedic I was working with the other day recommended that I use your website as a resource for cardiology. I really had hardly any understanding of axis calculation until I started reading this section yesterday, and now I can look at a 12-lead…
