This chapter details a systematic approach to interpreting electrocardiograms. The method is explained and then I take you through the approach on three practice ECGs.

During this chapter, we will practice reading electrocardiograms using the ECG reading format outlined in the “Guidelines For Electrocardiogram Interpretation” chapter. I will take you step-by-step through the process and interpret several electrocardiograms. (ECG #1-3)

With this ECG, we will take a completely different approach to the interpretation. I want you to look at the diagnoses made by the computer, and see if you agree or disagree. You need to defend your positions. After making your decisions, listen to the detailed explanations. You may want to read the ECG from beginning to end, as usual, and make your final diagnoses.
