Implication
EEG during tilt testing reveals subtype-specific cerebral responses; leaves open utility in guiding therapy for recurrent syncope.
Structured PICO
Does EEG monitoring during head-up tilt testing characterize cerebral events during tilt-induced vasovagal syncope in patients with recurrent syncope?
P
Population
63 consecutive patients with a history of recurrent syncope of unknown origin despite extensive clinical and laboratory assessment, mean age 41.5 years, 27 males and 36 females.
I
Intervention
EEG monitoring during head-up tilt testing
O
Outcome
Electrocerebral abnormalities (EEG modifications) during tilt-induced vasovagal syncopesurrogate
EEG monitoring during head-up tilt testing identifies distinct electrocerebral patterns, demonstrating that cardioinhibitory syncope causes more profound cerebral hypoperfusion than vasodepressor syncope.
