[|Human|] Hi.I am trying to understand a report of a carotitid ultrasound. Pulse waves are regular and there is no arrhythmia - I can understand.Not sure what the following mean,PS/ED Velocity,Distal CCA: 65/9 cm/sec,Max ICA: 84/24 cm/sec,ECA 87/13 cm/sec,ICA/CCA 1.29,Vertebral - antegrade flow
[|AI|]  How fast does the blood move while the heart beats (Peak systolic-PS)? 65 cm/s in the common carotid artery. The artery branches into an internal to the brain and external to the face. That are ICA and ECA. The 1.29 is a ratio. All the numbers are quite reassuring. When the arteries narrow, the velocities go up. Systolic over 350 and diastolic over about 85 are high. The flow in all the arteries should be forward, ante grade.
