- Mechanism first, morphology second
Mechanism explains the waveform. Morphology only displays it.
- Always determine atrial‑ventricular relationships
This single step clarifies most tachyarrhythmias. Many clinicians find that the use of laddergrams to be a significant aid in the determination of the atrioventricular relationship.
- Identify the source of ventricular activation
His‑Purkinje vs myocardium determines QRS width and shape.
- Revisit electrophysiology fundamentals regularly
Mechanisms deepen with repetition.
- Use a structured approach every time
Consistency prevents error.
Conclusion
Mechanism‑based ECG interpretation produces clinicians who understand the electrophysiology behind the waveform and can interpret ECGs with accuracy and confidence.
