What is ECG?
An electrocardiogram (ECG / EKG) is an electrical recording of the heart and is used in the investigation of heart disease.
How to read ECG?
This is one of the systematic approach how to read ECG:
1. Check the patient details - is the ECG correctly labelled?
2. What is the rate?
3. Is this sinus rhythm? If not, what is going on?
4. What is the mean frontal plane QRS axis (You may wish at this stage to glance at the P and T wave axes too)
5. Are the P waves normal (Good places to look are II and V1)
6. What is the PR interval?
7. Are the QRS complexes normal? Specifically, are there:
o significant Q waves?
o voltage criteria for LV hypertrophy?
o predominant R waves in V1?
o widened QRS complexes?
8. Are the ST segments normal, depressed or elevated? Quantify abnormalities.
9. Are the T waves normal? What is the QT interval?
10. Are there abnormal U wave
