This type of syncope occurs when there is a drop in bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure upon moving from a lying or sitting position to a standing one.
The underlying mechanism is related to the effect of gravity, which causes temporary pooling of bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood in the veins of the legs. This reduces the amount of bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood returning to the heart and consequently lowers bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure.

Syncope related to carotid sinus syndrome is a type of reflex syncope, meaning a brief loss of consciousness caused by an overreaction of the nervous system.

Situational syncope is part of the reflex syncope family, just like vasovagal syncope. It is triggered by a specific situation that causes an exaggerated reaction of the nervous system, leading to a drop in bloodBlood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells are responsible for transporting oxygen and carbon dioxide. White blood cells make up our immune defense system. Platelets contribute to blood pressure.
It can occur, for example, during a coughing fit, a forceful sneeze, or after urination.
Elle peut survenir, par exemple, lors d’une quinte de toux, d’un éternuement violent ou après avoir uriné.

Vasovagal syncope belongs to the family of reflex syncopes and is by far the most common type. It is estimated that one in four people will experience at least one episode of vasovagal syncope in their lifetime.
In most cases, it is triggered by prolonged standing, particularly in a warm environment, intense emotional stress, or sudden pain.
