Vasovagal syncope or common faint is the most frequent form of syncopes. With regard to the different involvement of the efferent mechanisms, several forms of the neurally mediated syncope syndromes are recognized. The authors present a case of mixed type vasovagal syncope, diagnosed by tilt table testing. The efferent mechanisms of syncope included Wenckebach type atrioventricular block due to increased vagal tone, and sympathetic withdrawal, reflected by sudden drop in the blood pressure. The significance and interrelationship of these factors are discussed.
