1.因心脏有节律性的收缩和舒张,因此引起动脉内的压力亦一升一降,从而引起动脉壁的弹性扩张与回缩的搏动,在表浅动脉的皮肤上可触及,称为脉搏。常检查近手腕处的桡动脉。脉搏的触诊内容有①速率;②节律;③紧张度;④强弱或大小;⑤脉搏的波状;⑥动脉壁的情况。 2.水冲脉常见于主动脉瓣关闭不全、甲状腺功能亢进等。其发生机理主要由于脉压差过大。交替脉见于左心功能不全。是由于心脏收缩一强一弱交替出现的结果。奇脉常见于心包积液和缩窄性心包炎。奇脉
1. Due to the rhythmic contraction and relaxation of the heart, the pressure inside the artery is also increased or decreased, causing the elastic expansion and retraction of the arterial wall to be pulsatile, which is palpable on the skin of the superficial artery. . Often check the wrist near the radial artery. Pulse palpation content ① rate; ② rhythm; ③ tension; ④ strength or size; ⑤ pulse wave; ⑥ arterial wall. 2. Common red water pulse aortic insufficiency, hyperthyroidism and so on. Its mechanism is mainly due to pulse pressure difference is too large. Alternating pulse seen in left ventricular dysfunction. Is due to a contraction of the heart of a strong one weak alternative results. Odd pulse common in pericardial effusion and constrictive pericarditis. Odd pulse
