目前认为颈动脉窦高敏征(Carotid Sinus Hypersensitivity,CSH)仍是晕厥不应忽视的原因之一。因而颈动脉窦综合征(Carotid Sinus Syndrome,CSS)的诊断及治疗日益为临床所重视。一、概述颈动脉窦是一压力感受器,刺激颈动脉窦可影响动脉血压、心率、心肌作功、心输出量、动脉阻力及静脉容量。CSH不同于CSS,是患者对颈动脉窦刺激异常敏感,而出现心脏抑制、血压降低等反应的现象。CSS则是CSH患者出现原因不明的眩晕、晕厥先兆或晕厥的一组临床症候群。CSS为一成年人疾病,发生率约为10％,多发生于50岁以后,且发病率随年龄而增长。好发年龄平均为60岁左右。男性患者较女性多两倍左右。且发现CSS常常与器质性心脏病有关,特别是冠心病和高血压。在老年男性高血压、冠心病患者的发病率
Carotid Sinus Hypersensitivity (CSH) is still considered one of the reasons syncope should not be ignored. Therefore, the diagnosis and treatment of Carotid Sinus Syndrome (CSS) are becoming more and more clinically important. First, an overview Carotid sinus is a baroreceptor stimulating the carotid sinus can affect arterial blood pressure, heart rate, myocardial function, cardiac output, arterial resistance and venous capacity. CSH is different from CSS, is the patient’s abnormal sensitivity to carotid sinus stimulation, and the emergence of cardiac inhibition, blood pressure and other reactions. CSS is a group of clinical syndromes of unknown cause of dizziness, faintness or syncope in CSH patients. CSS is an adult disease, the incidence of about 10%, occurred in more than 50 years of age, and the incidence increases with age. The average age of good hair is about 60 years old. Male patients more than twice as many women. And found that CSS is often associated with organic heart disease, especially coronary heart disease and hypertension. In elderly men with hypertension, the incidence of coronary heart disease
