What is neurocardiogenic syncope?

2 doctors weighed in across 2 answers

Reflex: It is a reflex, mediated by the vagus nerve, in which there is slowing of the heart rate and/or dilation of blood vessels - either/both resulting in a fall of blood pressure, diminished circulation temporarily to the brain, and loss of consciousness. Note: i see you have a pacemaker. While this prevents slow hr, it doesn't prevent vasodilation thus neurocardiogenic syncope is still possible.
