| Step | What to Look For | Quick Mnemonic | |------|------------------|----------------| | – Axis | QRS polarity in leads I and aVF → normal, left, right, extreme. | “I‑aVF = axis.” | | B – Basic Rhythm | Identify P‑waves, PR interval, QRS duration, rate. | “PR‑QRS‑QT.” | | C – Conduction | BBB, fascicular block, pre‑excitation, paced capture. | “BBB = wide QRS >120 ms.” | | D – Damage/Ischemia | ST‑segment deviation, T‑wave changes, Q‑waves. | “STEMI = 1 mm in 2 contiguous leads.” | | E – Everything Else | Electrolytes, drug effect, LVH criteria, etc. | “Don’t forget the ‘E.’” | A) Wide QRS complex (>120 ms) B) Left
is the ultimate hurdle. While the academy prioritizes "analyzing" over "memorizing," knowing the key concepts that frequently appear can help you bridge the gap between watching the videos and passing the test. | “PR‑QRS‑QT
