Self‐induced stretch syncope of adolescence: a video‐EEG documentation

Abstract

ABSTRACT We present the first video‐EEG documentation, with ECG and EMG features, of stretch syncope of adolescence in a young, healthy 16‐year‐old boy. Stretch syncope of adolescence is a rarely reported, benign cause of fainting in young patients, which can be confused with epileptic seizures. In our patient, syncopes were self‐induced to avoid school. Dynamic transcranial Doppler showed evidence of blood flow decrease in both posterior cerebral arteries mimicking effects of a Valsalva manoeuvre. Dynamic angiogram of the vertebral arteries was normal. Hypotheses concerning the physiopathology are discussed. [Published with video sequences] .
