Deceleration
Deceleration
Deceleration (/diːˌsɛləˈreɪʃən/) refers to the process of slowing down or reducing speed. It is often used in the context of Physics, where it describes a decrease in Velocity over time. In the medical field, deceleration can refer to a decrease in the rate of any physiological process, such as heart rate or breathing.
Etymology
The term "deceleration" originates from the Latin prefix "de-", meaning "down" or "away", and "celerare", derived from "celer", meaning "swift". Thus, it literally translates to "make less swift".

Medical Context

For example, deceleration in heart rate, known as Bradycardia, can be a sign of a healthy, well-conditioned heart, or it can be a symptom of a medical condition that requires treatment. Similarly, a deceleration in respiration rate, or Bradypnea, can be a sign of a relaxed state or a symptom of a medical condition.
