ICD-11 code : 8D89.0;
Preferred Label : Reflex syncope;
ICD-11 definition : Reflex syncope is a transient loss of consciousness with spontaneous recovery and
associated with loss of postural tone. Reflex syncope is the most common form of syncope
and can occur in individuals with normal autonomic function. The mechanism is believed
to be related to blood pooling in the legs followed by reduction in blood return to
the heart which triggers a sympathetic tone increase. Vigorous cardiac contractions
with an underfilled ventricle is hypothesized to cause reflex loss of sympathetic
tone and vagotonia.;
