==Sleep vasovagal syncope==
Sleep vasovagal syncope is defined as loss of consciousness in a non-intoxicated adult occurring during the night (e. g. 10:00 pm to 7:00 am), in which the patient wakes up with pre-syncopal and abdominal symptoms (i.e. an urge to defecate) and losses consciousness in bed or immediately upon standing.

There is no tongue biting or post-ictal confusion. There is usually a history of daytime vasovagal syncope and there seems to be a more pronounced fear of blood and medical procedures than in other syncope patients <cite>Jardine06b</cite>. Physical examination, ECG and EEG are within normal limits. The vasovagal reaction is thought to start while asleep <cite>Krediet04a</cite><cite>Jardine06a</cite>, and continuing after waking up, hence the name. During syncope there may be a profound sinus-bradycardia <cite>Krediet04a</cite>. Vasovagal sleep syncope occurs at all ages.
