True fact: I failed out/dropped out of grad school in mathematics. But despite having little enthusiasm for topology or complex analysis, nothing drives me more nuts than people who say stuff like “I’m not good at math – just not a math person, I guess.” This attitude is not just incorrect, it’s harmful. Most mathematics […]

Anterior T wave inversions and PE.

This is the conclusion to the previous case: 53 YOF with AMS: STEMI or Secondary ST-T changes? This female presented to the ED with Altered Mental Status (AMS), via ambulance, as STEMI ALERT, after completing approximately 3 hours of her usual dialysis. This was the 12 lead ECG provided by EMS…   We have a […]

During ECG interpretation, cardiac Axis, or direction of electrical impulses, may be normal (physiologic) or abnormal (pathologic), suggesting abnormal cardiac conductivity. Although every deflection obtained on the ECG will have an axis, we will focus on the ventricular axis. When we think of our cardiac monitoring lead placement, we have to understand cardiac Vectors, which is the […]

RBBB Abnormalities Missed

Entry Img

The original presentation of this case appeared as  "What's Wrong with Mr. Wilson?"… You can read the original post here. Much has been written lately about RBBB abnormalities that were missed.  Dr. Smith has recently posted two cases here, and here discussing this. First, let's review the 12 lead of a typical RBBB. When learning […]
