Postural Hypotension and Syncope in the Elderly
The abrupt loss of consciousness is the second most common reason why people seek emergency medical care. The very old have a 6 percent yearly incidence of syncope, and those who do faint have a recurrence rate of 30 percent . Vasovagal syncope, or the common faint, and psychogenic fainting are relatively less common in the elderly than in young persons. Serious treatable causes of syncope such as postural hypotension and cardiac arrhythmias are more frequent in the old (table 8–1).
