Arterial Stiffness and Dialysis Calcium Concentration
Figure 2
Arterial wave reflection. The upper section of both panels shows the recorded wave in subject with lower arterial stiffness (a) and higher arterial stiffness (b) as determined by a lower and a higher pulse wave respectively. The lower section of both panels shows the dissection of the recorded wave into the incidental (- - -) and reflected waves (…) in the respective conditions. In (a), it can be seen that the timing of peak reflected pressure wave (arrow) occurs after the closer of the valves (vertical line). In (b), the timing of peak reflected pressure wave (arrow) occurs before the closer of aortic valves (vertical line).
