Abstract:
|
A novel method to measure Pulse Transit Time (PTT)
from the force sensors of a modified electronic weighing
scale is presented. The method relies on the relation
between PTT and the interval between I and J waves of
the ballistocardiogram (BCG). The IJ interval and the
PTT derived from a carotid and a femoral pressure-pulse
waveform were simultaneously obtained from three
subjects during paced respiration, which induces periodic
hemodynamic changes. The correlation between the IJ
interval and this PTT is 0.69 and the difference between
measurements is -5.2±16.4 ms, which are values similar
to those of commercial devices based on more invasive
methods that can be applied only to subjects in supine
position. The simplicity of the method and the costeffectiveness
of the device to implement it offer new
perspectives for the ambulatory assessment of arterial
stiffness. |
