Five cases of carotid sinus syndrome are presented. The syndrome is defined by spontaneous attacks of dizziness and fainting which can be reproduced by graded pressure on one carotid sinus. Three forms of the clinical syndrome, cardioinhibitory, vasodepressor, and cerebral, are discussed. The hyperactive carotid sinsu reflex, in which there is ventricular asystole lasting at least 3 seconds or a decrease of more than 50 mm Hg in systolic and diastolic blood pressure, should be differentiated from this syndrome. Treatment modalities include reassurance, drugs, radiotherapy, cardiac pacemakers, and surgical approaches. Carotid sinus syndrome should be considered in the differential diagnosis of unexplained syncope, arteriovenous block, or inappropriate sinus bradycardia.
本文报告了5例颈动脉窦综合征。该综合征的定义为自发性头晕和昏厥发作，对一侧颈动脉窦施加分级压力可诱发此类发作。文中讨论了该临床综合征的三种形式，即心脏抑制型、血管减压型和脑型。高敏性颈动脉窦反射（表现为心室停搏至少持续3秒或收缩压和舒张压下降超过50 mmHg）应与该综合征相鉴别。治疗方式包括安慰、药物、放疗、心脏起搏器和手术方法。在不明原因晕厥、动静脉阻滞或不适当窦性心动过缓的鉴别诊断中应考虑颈动脉窦综合征。
