A patient with an adult Chiari malformation had syncopal episodes induced by modest exertion. Low-amplitude slowing of the electroencephalogram occurred at the time of syncope, with no change in pulse rate, blood pressure, or arterial gases in attacks reproduced by exercise, compression of jugular veins or standardized Valsalva maneuver. The attacks were attributed to transient increases in intracranial pressure that caused dysfunction of the ascending reticular activating system.
一名患有成人型Chiari畸形的患者在适度运动时出现晕厥发作。晕厥时脑电图出现低幅减慢，在运动、压迫颈静脉或标准化瓦尔萨尔瓦动作诱发的发作中，脉搏率、血压或动脉血气无变化。发作归因于颅内压短暂升高，导致上行网状激活系统功能障碍。
