1) Cause (Etiology)

Vasovagal reflection (vasovagal reflex)
Cough attacks by syncope (cough syncope (cough syncope)) also enter into this.

Postural hypotension (orthostatic hypotension)
Transient cerebral ischemia occurs when maintained a standing position without moving

Differentiation of cardiogenic syncope

Valvular heart disease for example:Aortic valve stenosis (Aortic stenosis)

Cardiac tamponade (Cardiac tamponade)
→ epicardial Maku腔 water is stored in, or epicardium becomes hard, that the ventricle is a state that can not be extended
