CARDIOLOGY QUIZ TIME
You’re the ER doc. Clock’s ticking ⏱️

58M, crushing chest pain, 90 min out. ECG screams STEMI.

What’s your FIRST move to save the muscle?

A, B, C or D? 👇

Most interns miss this.
Cardiologists don’t.

Drop your answer + why. I’ll pin the best explanation in 12 hrs.

🫀 ECG Challenge Time! 🫀
Only 20% of learners get this right on the first try. Are you one of them

A QRS complex that is isoelectric in Lead aVF and positive in Lead I gives us an important clue about the heart's electrical axis.

📊 Can you determine the approximate cardiac axis?

🔹 A) 0°
🔹 B) +90°
🔹 C) -90°
🔹 D) +180°

💡 Drop your answer in the comments and explain your reasoning if you can!

👨‍⚕️ Whether you're a medical student, cardiac technician, nurse, or ECG enthusiast, this is a great way to sharpen your axis interpretation skills.

✅ Answer and explanation will be revealed soon.

🚨 Most techs know the names of cardiac biomarkers.

Very few know the pearls that prevent mistakes.

Can you explain:
✅ Why a positive troponin doesn't always mean MI?
✅ When CK-MB is still useful in 2026?
✅ Which BNP cutoffs actually matter?
✅ Why D-dimer can be misleading?
✅ The one mistake people make with myoglobin?

The answers are hidden in today's subscriber-only chart 👀

V1 to V6 — the 6 leads that show us the heart’s story from right to left 🫀

Saving this one for all my med friends, students, and anyone who’s ever stared at an ECG wondering _“where exactly are they looking?”_

This breaks down chest lead placement, what each one sees, normal R wave progression, and how they help spot an MI or hypertrophy.

Remember: V1 = Right, V6 = Left. Small R → Big R across the chest.

Decoding ECG Basics: aVR, aVL, aVF 🫀📊

The augmented limb leads are often skipped, but they’re critical for reading axis, spotting inferior MIs, and getting the full 360° view of the heart.

*Quick memory aid: "Right - Left - Feet"*
aVR → Right shoulder → Usually negative (-150°)
aVL → Left shoulder → Small positive (-30°)
aVF → Feet → Positive (+90°)

Together with I, II, III they complete the frontal plane. Master the leads, own the ECG.

*Clinical pearl:* ST elevation in II, III, aVF with ST depression in aVR = Think inferior wall MI

🫀📚 ECG LEADS MCQs

Understanding ECG leads is the foundation of accurate ECG interpretation. From septal and anterior leads to lateral lead placement — every lead tells a different story about the heart. ❤️⚡

Test your knowledge with these quick MCQs and strengthen your basics in cardiology and ECG interpretation.

✅ V1–V2 → Septal leads
✅ V3–V4 → Anterior leads
✅ V5–V6 → Lateral leads
✅ Correct lead placement = Better diagnosis

CARDIAC MARKERS MCQs 🫀📋

Can you answer all 5 correctly? 🤔

Troponin vs CK-MB vs BNP vs Myoglobin — if you’re a med student, nursing student, or prepping for NEET PG, this one’s for your saves.

Drop your score below 👇 5/5 or 4/5?

📌 Key Takeaway: Rising Troponin + CK-MB = Acute MI. Serial testing is crucial.
