How often is dizziness from primary cardiovascular disease true vertigo? A systematic review.

Objectives: To assess how frequently cardiovascular dizziness is vertigo. Recent studies suggest providers do not consider cardiovascular causes when a patient reports true vertigo (spinning/motion) as opposed to presyncope (impending faint). It is known that cardiovascular disease causes dizziness, but unknown how often such dizziness is vertiginous, as opposed to presyncopal.

Overreliance on symptom quality in diagnosing dizziness: results of a multicenter survey of emergency physicians.

Objective: To assess emergency physicians' diagnostic approach to the patient with dizziness, using a multicenter quantitative survey.

Participants And Methods: We anonymously surveyed attending and resident emergency physicians at 17 academic-affiliated emergency departments with an Internet-based survey (September 1, 2006, to November 3, 2006). The survey respondents ranked the relative importance of symptom quality, timing, triggers, and associated symptoms and indicated their agreement with 20 statements about diagnostic assessment of dizziness (Likert scale).
