Morphology
sinus + tachy
This is a specialist medical abbreviation (sinus tachy for sinus tachycardia) built from Greek-derived roots that are not common knowledge at B1; the supplied constituent entries are undefined, and a learner who only knows everyday senses of 'sinus' (e.g. nasal cavity) and not the medical prefix 'tachy-' would not infer 'abnormally rapid heartbeat.' Understanding the term requires domain-specific knowledge of cardiac anatomy and medical morphology, so the meaning is not transparently derivable from the parts for an average B1 learner.
Etymology
Sinus tachy is a medical short form made of two parts: sinus for the heart's natural pacemaker called the 'sinus node', and tachy from a Greek root meaning 'fast'. So sinus tachy pictures a 'fast' heartbeat coming from the 'sinus node', which is why it means a rapid heartbeat that starts there.
