9.4 Method
Ten pulse waves are filtered and averaged to determine the central
arterial pulse wave. The augmentation index is standardised for a
pulse rate of 75 bpm (see reference [1]). This parameter is then
described as Alx@75.
Alx@75 has been analysed in a representative cross-section of the
population (see reference [2]), and an age-dependent estimate for the
Alx@75 plus the respective confidence interval have been assessed.
These relevant analyses have also shown that there is a significant
difference for the average Alx@75 between men and women.
