Clinical Pearls for Avoiding ECG Interpretation Errors
- Always identify the mechanism before the morphology
Mechanism drives appearance.
- Look for AV dissociation in every WCT
It is the single most useful discriminator.
- Never diagnose STEMI without considering mimics (see the book Getting Acquainted With Ischemia and Infarction)
Mechanism first, millimeters second.
- Revisit electrophysiology fundamentals regularly
Mechanisms deepen with repetition.
- Use a structured approach every time
Consistency reduces error.
Conclusion
Avoiding ECG mistakes requires a mechanism‑based framework, not pattern recognition. These clinical pearls help clinicians interpret ECGs with accuracy and confidence.
