Prehospital ECGs and STEMI Receiving Centers
An important paper has been published that deserves to be read in its entirety. Rokos IC, French WF, Koenig WJ, et al. Integration of pre-hospital electrocardiograms and ST-elevation myocardial infarction receiving center (SRC) networks: Impact on door-to-balloon times across 10 independent regions. J Am Coll Cardiol Cardiovasc Intervent 2009; 2:339-346 Here are some highlights: “There […]
Things that make you go hmmm
It seems incredible that we can email a photograph around the world, but we haven't yet found an easy way of transmitting an ECG to a nearby hospital. – Ivan Rokos, MD to heartwire [1] Question: What's the incentive for industry to invent a simple, cost effective method for transmitting the prehospital 12 lead ECG […]
Top 10 myths about prehospital 12 lead ECGs
A recent thread at JEMS Connect has reminded me how many myths are circulating about prehospital 12 lead ECGs. 1.) If you’re close to the hospital, performing a prehospital 12-lead ECG is a waste of precious time. The prehospital 12-lead ECG is an important triage tool. The closest hospital is not necessarily the closest appropriate […]
Recurrent syncope and bifascicular block
You are dispatched to an “unknown medical complaint.” En route to the scene, dispatch advises you that a 66 year old male is complaining of a fall with injury, chest pain, left arm pain, and nausea. On arrival, the patient is standing in his kitchen. He is pale and extremely diaphoretic. You direct him to […]

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…
