| atrium |
In anatomy, the atrium (plural: atria) is the blood collection chamber of a heart. It has a thin-walled structure that allows blood to return to the heart. There is at least one atrium in an animal with a closed circulatory system. In fish, the circulatory system is very simple: a two-chambered heart including one atrium and one ventricle. In vertebrate groups that evolved later, the circulatory system is much more complicated. ...

| Atractaspis |
A small, unusual group of advanced snakes, often called mole vipers or stilleto snakes. Recently, molecular evidence has shown that this family includes many genera formerly classed in other families, on the basis of fang type. This odd family of snakes seems to include fangless (aglyphous), rear-fanged (opisthoglyphous), fixed-fanged (proteroglyphous), and viper-like (solenoglyphous) species. ...

| atrial fibrillation |
Atrial fibrillation (AF or AFib) is a cardiac arrhythmia (an abnormality of heart rate or rhythm) originating in the atria. Abnormal electrical impulses in the atria cause the ventricles to contract erratically. AF is the most common cardiac arrhythmia. If rapid, it may compromise blood flow and cause fainting, orthostatic hypotension (low blood pressure on standing up) or low blood pressure. ...
