By the end of the lesson students should be able to understand…

• the basis for the ECG waveform
• what the 12 leads mean
• cardiac electrophysiology
• a systematic approach to ECG interpretation
• practice a systematic approach to ECG interpretation
• learn how to determine cardiac rhythm

Part 1: Revision of Normal ECG

• Here’s a diagram showing the normal ECG, and how it relates to different parts of the cardiac cycle…
• Where is the heartbeat initiated?
• Where does the impulse then go?
• Then where does it go?
• Ok understood… then where?
• What does the QRS complex denote?
• What’s the ST segment on the ECG?
• And finally, what’s the T wave?
• On a standard ECG, why do we see 12 leads?
• Explain which ECG leads let us view the different parts of the heart…
