Does electrical oesophageal stimulation elicit different cortical evoked potentials and autonomic responses in patients with noncardiac chest pain compared to healthy controls?
Patients with noncardiac chest pain exhibit increased perception of oesophageal stimuli associated with enhanced cerebral processing and a greater cardiovagal reflex response, rather than hyperalgesic responses in visceral afferent pathways.
Hollerbach et al. (2000) studied this question.
