Morphology

ventricular + fibrillation

The term is directly compositional: 'ventricular' specifies the location (the ventricles) and 'fibrillation' denotes chaotic, uncoordinated contractions, so combined they mean chaotic contractions of the ventricles. While both words are medical and may be unfamiliar to a typical B1 learner, if the learner knows the constituent meanings the overall sense is predictable and follows standard modifier+noun composition.

Etymology

Ventricular fibrillation describes a clear picture: the heart's lower parts, the ventricles, begin to twitch like loose fibers, which is why doctors call the shaking 'fibrillation'. So, it means a dangerous, irregular heartbeat that can make the heart 'stop'.
