Data viva — the mediastinum and coronary supply
A Primary anatomy data viva — read the ITMIG three-compartment mediastinum (prevascular, visceral, paravertebral) with the superior mediastinum in clinical use; map the RCA to the inferior wall and nodes; explain that RCA occlusion causes bradycardia and AV block.

Prompt
A Primary anatomy data viva — read the ITMIG three-compartment mediastinum (prevascular, visceral, paravertebral) with the superior mediastinum in clinical use; map the RCA to the inferior wall and nodes; explain that RCA occlusion causes bradycardia and AV block.
Stimulus
A labelled sagittal diagram shows the ITMIG three-compartment mediastinum with a superior-mediastinum overlay; a separate inset shows the right coronary artery supplying the inferior wall via the posterior descending artery plus the sinoatrial and atrioventricular nodes. Talk through the mediastinal divisions, give the RCA supply and what dominance means, and explain why an inferior MI causes bradycardia.[1][2]
