Swallow syncope is associated with transient and temporally independent CI and VD features, consistent with reflex syncope. Potentially, a swallowing test during autonomic evaluation may be useful to unmask relative magnitudes of CI and VD responses, thereby facilitating treatment strategy decisions.
