The Atrial septum The wall between the two atriums is called the septum. Septum Cardiac Septum Atrial septum, containing the foramen ovale. Actually its called the interatrial septum...
The upper chambers of the heart are called atria, and the wall that separates them is called the atrial septum. Thus a defect in that wall is called an atrial septal defect. They are not uncommon, and can run in families and be associated with genetic abnormalities such as Down syndrome.
The atrial septum divides the upper chambers of the heart, the left and right atria, preventing blood from mixing between them.
One separating the atrium and ventricle is called atrial septum and ventricular septum respectively.
The interatrial septum separates the left and right atria.
It is called Atrial Fibrillation
A flap-like lateral wall of each atrium is called the auricle. Its purpose is to increase the atrial volume, thereby increasing the efficiency of blood flow into the ventricles.
The wall between the left and right side of the heart is called 'Septum'.

Atrial Flutter. You may be thinking of atrial fibrillation, though.
i belive its called paroxysmal artrial trachycardia
It's Atrial Natriuretic Peptide also known as Atrial Natriuretic Factor or Atrial Natriuretic Hormone or sometimes called Atriopeptin
