atrial
Of heart antechambers
Atrial means relating to an atrium—either a chamber of the heart or an architectural space.
In medicine, atrial usually refers to the upper chambers of the heart: atrial fibrillation, atrial flutter.
The term appears in cardiology contexts describing rhythm disorders, septal defects, and other conditions affecting these chambers.
