• Step 1: Rhythm
• Step 2: Rate
• Step 3: Conduction (PQ,QRS,QT)
• Step 4: Heart axis
• Step 5: P wave morphology
• Step 6: QRS morphology
• Step 7: ST morphology
• Step 7+1: Compare the current ECG with a previous one
• Step 7+2: Conclusion

Finally the real world is presented through practice ECGs.

If you have finished the course you are invited to come back to read more about abnormal ECGs in the ECG textbook.
