Simple blue breath holding attacks : consist of a positive Valsava manoeuvre , cyanosis , stiffening , and coma .They may be seen usually after the age of six months and are provoked by frustration or other upset . White reflex asystolic attacks : consist of vagal asystole , pallor , rapid coma , stiffening and opisthotonos . They may start earlier and usually follow minor injury . Faints while standing or sitting are usually well recognised . All three conditions may be accompanied by late true epileptic phenomena or jerking secondary to cerebral hypoxia or ischaemia , but their natural history remains self-limiting and harmless like that of the first episode .
