Data viva — the conduction system and the ECG
A Primary data viva — map each ECG deflection to its conduction structure; explain the funny current and AV-nodal delay; describe concealed conduction and the three arrhythmia mechanisms.

Prompt
A labelled diagram of the cardiac conduction system is shown beside a surface ECG (P wave, PR segment, QRS, T wave). Relate each ECG feature to its underlying conduction event, and explain how the AV node protects the ventricles during atrial fibrillation.
