Morphology

atrial + fibrillation

The meaning is directly compositional: 'atrial' specifies the atria (upper heart chambers) and 'fibrillation' denotes chaotic, uncoordinated contractions, so a learner who knows both constituents can infer an irregular/chaotic heartbeat in the atria. Although medical terminology, the lexical parts combine in a predictable, cross-linguistically common way, making the phrase transparent.

Etymology

The term atrial fibrillation paints a simple picture: atrial means the heart's top chambers and fibrillation means 'trembling' or 'quivering'. So the heart's upper chambers flutter instead of beating steadily, which is why the phrase describes an irregular, often fast heartbeat.
