She had a shock state

Explanation:

Syncope is a symptom defined as sudden and transient loss of consciousness secondary to diffuse cerebral hypoperfusion. Usually presents sudden onset, short duration and spontaneous recovery. This sycope is due a "shock state".

Shock state is a group of acute cardiovascular syndromes that have no character and a unique definition that understands all its various causes and origins. It occurs when there is a malfunction between the heart, blood vessels (arteries or veins) and the blood, by setting up an imbalance in the body.  The causes can be various: external or internal trauma, sudden perforation of organs, emotion, cold, burns, surgical interventions, etc.
