! Seek urgent medical care if warning signs appear
Some health conditions or symptoms can become urgent. Use this page for education, but seek help quickly if warning signs are present.
Get urgent medical care now if there is any severe, sudden, rapidly worsening or worrying symptom, especially:
- chest pain, pressure or pain spreading to the arm, jaw or back
- trouble breathing, blue lips, severe wheeze or choking
- stroke-like symptoms such as face drooping, arm weakness or speech trouble
- collapse, fainting, seizure, confusion or extreme drowsiness
- severe bleeding, black stools, vomiting blood or major injury
- severe allergic reaction, swelling of the face/throat or widespread rash with breathing trouble
- severe abdominal pain, severe headache, stiff neck or sudden vision change
- signs of severe dehydration, sepsis, high fever with worsening illness, or symptoms in a baby/young child that concern you

Introduction / full article
Atrial Septal Defect
Atrial Septal Defect
The human heart comprises four chambers which can each be identified uniquely as being upper or lower, and left or right. The two chambers on the left of the heart are responsible for pumping oxygen-rich (arterial) blood throughout the body. Meanwhile, the right chambers receive and pump de-oxygenated (venous) blood to the lungs, where it is ‘refilled’ with oxygen.
Atrial septal defect (abbreviated to ASD) is a birth defect in which the muscle wall (septum) dividing the heart into its left and right halves has a hole, enabling blood to flow between the two halves. The result is mixing of the arterial and venous blood, which can have serious implications for the circulatory system’s ability to supply adequate oxygen and nutrients to each cell of the body.
