Relative Atrial Index
Relative Atrial Index
The Relative Atrial Index (RAI) is a medical term used in the field of Cardiology. It is a measure used to assess the size of the atrium in relation to the overall size of the heart.
Pronunciation
Relative Atrial Index is pronounced as /ˈrɛlətɪv ˈeɪtriəl ˈɪndɛks/.
Etymology
The term is derived from the English words "relative", "atrial", and "index". "Relative" comes from the Latin word "relativus", meaning "relative" or "comparative". "Atrial" is derived from the Latin word "atrium", which refers to the upper chambers of the heart. "Index" comes from the Latin word "index", meaning "indicator" or "pointer".
