Patient history significant for prior MI requiring 3 stents. No other significant history. Patient denies any CP, SOB, N/V, lightheadedness. In fact, he denies any complaints at […]

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.

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…
