颈动脉窦按摩力法 病人取仰卧位,头略向后转。首先作颈动脉触诊和听诊,排除其内在疾病。然后在下额角下方颈动脉分叉处按摩5秒钟。每次只按摩一侧。有人采用颈动脉加压,这样可较多地重复操作。疑为颈动脉窦过敏者应取坐位进行,开始操作轻柔,无效再以较强的力量反复按摩。操作过程中应有心电监护。 正常反映 颈动脉窦按摩可使窦性频率暂时减慢及房室结传导延缓。引起窦性静止的正常上限为3秒。可导致P波形态改变。很少引起希一蒲系统阻滞。有的认为右颈动脉窦对窦房结影响较大,左颈动脉窦则对房室结影响较大。血被动力学影响心 Carotid sinus massage patients take supine position, head slightly backward. First carotid palpation and auscultation, excluding its internal disease. Then massage for 5 seconds at the bifurcation of the carotid artery below the beard. Only massage one side at a time. Some people use the carotid artery pressure, so you can repeat the operation. Suspected carotid sinus allergy should take seats, began to operate gentle, ineffective and then repeatedly massage with a strong force. The operation should have ECG monitoring. Normal reflection of carotid sinus massage can make sinus frequency temporarily slowed down and atrioventricular node conduction delay. The normal upper limit causing sinus rest is 3 seconds. Can lead to changes in P wave morphology. Rarely caused Xi Yipu system block. Some believe that the right carotid sinus sinus node greater impact on the left carotid sinus atrioventricular node greater impact. Blood dynamics affect the heart
