Namely, in addition to procedural complications in the medical setting and the risk of fall and injury caused by loss of consciousness, some patients with vasovagal syncope may also suffer from comorbidities, such as cardiac arrhythmias, structural cardiopulmonary disease, cerebrovascular disease, andneurological conditions,such asseizure,stroke,and migraine. The ECG, however, showed a pronounced bradycardia (36 beats/min) during the episode, with an atrioventricular node escape rhythm.

But there are several other possible mechanisms by which the brainstem may be transiently overridden: firstly, asymmetrical slow wave activity in the cortex10; secondly, rapid changes in sympathetic activity occurring during the transition between the stages of sleep11; thirdly, cortical inhibitory discharge as the result of a nightmare4; and lastly, gastrointestinal afferents firing paradoxically in response to visceral stimuli, as in defecation syncope.12 We consider that the final possibility is unlikely to occur and that abdominal discomfort is more likely to be an effect rather than a cause of increased vasovagal activity in our patients.13 There are several mechanisms by which major changes in visceral autonomic tone may cause abdominal pain.14.
