Heart failure

Atrial fibrillation is a heart rhythm disorder that is usually chronic. It is considered a risk factor for stroke. If atrial fibrillation is treated appropriately, most people can still lead a normal life.

Shock is a severe circulatory disorder in which the body is no longer supplied with sufficient blood and oxygen. This results in all organs being deprived of blood and oxygen, and ultimately leads to metabolic failure. Shock is a life-threatening condition and, if left untreated, leads to death within a very short time.
