Syncope is highly prevalent in the general population, particularly among females, and is primarily triggered by orthostatic and vasomotor factors.
In conclusion, our study shows that the lifetime cumulative incidence of syncope in the general population is high. Females experience syncope more often than males. The majority of the syncope triggers were related to conditions that affect orthostatic blood pressure regulation and vasomotor responses.
Ganzeboom et al. (Tue,) studied this question.
