03 The ECG | Notion

Describe how electrical activity in individual myocytes produces the ECG
Relate how depolarisation and repolarisation throughout the heart produces the P-QRST waveform of the healthy ECG
Describe the sequence of conduction of the waves of depolarisation which produce the P wave and the QRS complex
Describe the sequence of repolarisation which produces the T wave
Explain why atrial repolarisation is not seen in the healthy ECG waveform
Identify what type of deflection on the ECG recording will be produced by a wave of excitation heading toward the positive electrode, or a wave of repolarisation heading away from the positive electrode
Identify what type of deflection on the ECG recording will be produced by a wave of excitation heading away from, or a wave of repolarisation heading toward, the positive electrode
Explain the isoelectric line
Describe electrode placement in 12 lead ECGs (in conjunction with Clinical Skills)
Compare and contrast normal ECGs traces from leads I, II, III, aVR, aVF, aVL, V1V6
