ABSTRACT
Objectives To analyse the etiology and clinical characteristics of syncope in children. Methods The clinical data of 128 children with syncope were retrospectively analyzed. Results According to the definition of syncope and supporting test results, 20 cases of non-syncopal conditions were excluded. In 108 cases of syncope, there were 70 cases (64.81%) of neurally mediated syncope, 8 cases (7.41%) of cardiogenic syncope, and 24 cases (22.22%) of unexplained syncope. Eighty-five cases (78.71%) had incentives before the onsets. Twenty-one cases (19.44%) had the family histories of syncope. One case (0.93%) had the family history of sudden death. The neurally mediated syncope and cardiogenic syncope had the feature of recurrent attacks. The VVS were preceded by limbs weakness, pale complexion, darkness in front of eyes, hearing loss, nausea and chest pain, the POTS by palpitation, chest pain and weakness, the OH by darkness in front of eyes, pale complexion and hearing loss, and the car-diogenic syncope by precordial discomfort, pain and chest pain. Conclusions The VVS is one of the most common cause of syn-cope in children. The onsets of the various types of syncope often have incentives and are preceded by some symptoms. Most of them have the feature of recurrent attacks.
