Morphology
atrioventricular + nodal + rhythm
The phrase is compositionally built from technical constituents: 'atrioventricular' (relating to atria and ventricles) + 'nodal' (of a node) + 'rhythm' (a pattern of beats), so its meaning as a cardiac rhythm produced by the atrioventricular node is directly derivable. Although clinical knowledge helps to interpret implications (e.g. control vs. sinoatrial node), the lexical combination itself follows predictable compounding patterns, making it transparently interpretable to someone who knows the component terms.
Etymology
Atrioventricular nodal rhythm literally names where the heartbeat comes from: the atrioventricular area between the heart's top and bottom chambers and the small node there set the rhythm. So it means 'the heart is controlled by the atrioventricular node' when the usual pacemaker stops.
