Dizzyness/syncope Flashcards
0
Q
Vasovegal vs. cardio syncope
A
- vaso vegal ~ 2.5 minutes
- cardiogenic ~ 3 seconds
~ as soon as the go down, brain reprofuses
~ postural syncope has better prognosis
1
Q
syncope vs. seizure
A
- post ictal confusion is strong indicator of seizure and NOT syncope
- seizure will probably have aura
- diaphoresis and amnesia
2
Q
Post ictal confusion in syncope
A
- should not last longer than a few seconds
3
Q
Syncope -> seizure
A
- seizure like symptoms can occur if held in upright position
- don’t misdiagnose for seizure
4
Q
Positional hypotension criteria
A
- orthostatic drop in 20/10
- increase in hr < 20 BPM
5
Q
Peripheral vs. central vertigo
A
- central: occulocephalic reflex is intact, intact visual acuity with head movements
- peripheral: occulocephalic reflex not intact
~ usually vomiting and begging for it to stop
6
Q
Dix-Hallpike
A
Positioning test to establish benign paroxysmal positional vertigo
7
Q
BPPV
A
- benign paroxysmal positional vertigo
- typically will have poor balance, and prefer to lie down during spell
8
Q
Miniers disease triad
A
- episodic vertigo
- tinnitus
- hearing loss
9
Q
Miniers disease: pathenogenesis, trt
A
- lots of etiologies
- chronic otolethiasis
- corticosteroid, salt reduction
10
Q
Vestibular neuronitis
A
- most common cause of acute vertigo
- generally viral, and self resolving in a few days
- vertigo without auditory symptoms
- roids and antiemetics
11
Q
Bilateral vestibular loss
A
- complaints of mild symptoms (since both sides are lost)
- include gait and postural abnormalities
- always positive rhomberg (eyes open/eyes closed, no difference)
12
Q
Central causes of vertigo
A
- migraine
- CVD
- MS
- masses/malformations (uncommon, slow progressive
- psych (will be associated with psych symptoms; hyperventilation will recreate these symptoms)
