Lesson II - A "Method of ECG Interpretation
II. A "Method" of ECG Interpretation
Frank G. Yanowitz, MD
Professor of Medicine

This "method" is recommended when reading all 12-lead ECG's. Like the
physical examination, it is desirable to follow a standardized sequence of steps
in order to avoid missing subtle abnormalities in the ECG tracing, some of which
may have clinical importance. The 6 major sections in the "method" should be
considered in the following order:
1. Measurements
2. Rhythm Analysis
3. Conduction Analysis
4. Waveform Description
5. Ecg Interpretation
6. Comparison with Previous ECG (if any)
1. Measurements (usually made in frontal plane leads):
Click to view
Heart rate (state atrial and ventricular, if different)
PR interval (from beginning of P to beginning of QRS)
QRS duration (width of most representative QRS)
