[Syncope or palpitations during pregnancy].

Syncope and palpitations are common symptoms during pregnancy ; they are elicited by physiological changes. Although they are often benign, careful management is essential to eliminate a serious aetiology requiring specialized care. Syncope is often of vasovagal origin, but trauma with possible secondary lesions that compromise the life-threatening of the mother and foetus must be researched. Some palpitations are the manifestation of serious rhythm disorders whose therapeutic management depends on their severity and must consider the potential side effects on the foetus.
