Vasovagal syncope (VVS), a clinical problem with high morbidity, seriously affects patients" life style, therefore appropriate prophylaxis and treatment of VVS are imperative.Though 13-blockers, theophylline, and scopolamine have shown curative effects on VVS, their use are limited due to side effects. We hypothesize that irbesartan, an angiotensin [I receptor antagonist, can be used to treat VVS with no limitation especially in small dosage.【Clinical Observation of Irbesartan in Treatment of Vasovagal Syncope】完成机构：InternationalHealthCareCenter,theFirstAffiliatedHospitalofMedicalCollege,ZhejiangUniversity,Hangzhou310003
