A decrease of more than 20mm Hg in the systolic pressure is considered abnormal as is a drop in pressure below 90mm Hg independent of the development of symptoms.
Neurologic Syncope Neurologic causes of apparent syncope include seizures, TIAs, migraine headaches and subclavian steal syndrome.
A rule that considers patients with an abnormal ECG, a complaint of shortness of breath, hematocrit less than 30%, systolic blood pressure less than 90 mm Hg, or a history of congestive heart failure has 96% (95% confidence interval [CI] 92% to 100%) sensitivity and 62% (95% CI 58% to 66%) specificity.
If applied to this cohort, the rule has the potential to decrease the admission rate by 10%.
