The 360 Degree Heart – Part I

Entry Img

The hexaxial reference system. If I asked you to imagine how the limb leads “look” at the heart, you would probably picture something like the image below: Notice those gaps in the limb leads? They don’t really exist. They’re an illusion. This isn’t something that is commonly emphasized when the cardiac axis is being taught, […]

My apologies for the faded ECGs. Turns out the medic (a recent grad from our hospital’s program) had been carrying them in his work pants for over a week, waiting to catch me in the ED. The  patient had been brought to another hospital, but he wanted to review the ECGs with me. They had […]

[…]

59 year old male: chest pressure
Besides MI and Aortic Dissection, this presentation of acute chest pain and hemodynamic compromise, associated with important dyspnea would concern me for PE, which I think should be properly investigated.
