Symptom onset

Prior diagnosis of transient ischemic attack, stroke, vertebrobasilar insufficiency, migraine, seizures, benign paroxysmal positional vertigo (BPPV), vestibular neuritis, concussion, Meniere’s disease, or orthostatic hypotension

Triggers & Associated Signs and Symptoms

Bedside Exam Techniques to Consider

Dizziness is episodic and triggered only by head/position changes (benign paroxysmal positional vertigo, orthostatic hypotension or postural orthostatic tachycardia syndrome – consider Dix-Hallpike/Epley maneuver and checking orthostatic vitals)

Positive orthostatic hypotension: reduction of in systolic blood pressure (SBP) of >20 mm Hg OR a reduction of in diastolic blood pressure (DBP) >10 mm Hg

Postural Orthostatic Tachycardia Syndrome (POTS): sustained heart rate increase of 30 beats per minute (bpm) or more, or over 120 bpm, within the first 10 minutes of standing, in the absence of orthostatic hypotension
