Fever is described with the term pyrexia. Pyrexia refers to an elevated body temperature, typically above the normal range (around 36.5–37.5°C or 97.7–99.5°F), often caused by the body's response to infection, inflammation, or other stimuli. The other terms refer to different conditions: hypertension is high blood pressure; hypothermia is an abnormally low body temperature; arrhythmia is an irregular heartbeat. So pyrexia is the correct term for fever.
