A step by step framework you can use on every ECG - on exams, on rounds, and for real patients

Build the mental framework everything else depends on
Cardiac anatomy & intro
Hemodynamics 101
ECG paper, waveforms, intervals, and timing
Vectors, axis, and why leads look the way they do
Lead II interpretation made simple
Heart blocks explained without memorization
Knowledge check to lock it in
Turn tracings into decisions, not guesswork
A repeatable 12-lead interpretation workflow
Localizing ischemia and infarction by lead patterns
STEMI territories and reciprocal changes
Subtle STEMI & OMI patterns most people miss
Ventricular tachycardia: recognizing dangerous variants
Advanced Atrial flutter
AVNRT
“Cardiac Seizure” mimics
Pacemakers & rate-related ECG changes
Electrolyte abnormalities
Knowledge Check
WPW & AVRT
STEMI equivalents
STEMI mimics
Cardiomyopathies
Advanced Topics
Final knowledge checks for mastery





You want to learn how to interpret 12-lead ECGs faster and with confidence - without memorizing endless rules
You value clarity, pattern recognition, and real-world application over academic fluff
People who want a repeatable system you can use on shift, during exams, and in high-pressure scenarios
Students preparing for exams, rotations, and boards
Nurses who want to truly understand what they’re seeing on the monitor
Paramedics & EMTs who need rapid, actionable ECG interpretation in the field
New grads who feel overwhelmed by ECGs and want a simple framework
Experienced clinicians who can “recognize” rhythms but want deeper confidence
And anyone tired of guessing and second-guessing ECGs
You prefer to figure things out on your own with hours of trial and error
You prefer memorizing dozens of obscure rules without understanding why
