The Association of Radial Artery Pulse Wave Variables with the Pulse Wave Velocity and Echocardiographic Parameters in Hypertension

Figure 2

The time-domain variables of pulse signal. Notes: this pulse signal sample is a triple-peak waveform, which includes the main wave, the tidal wave, and the dicrotic wave. The y-axis is the amplitude of the pulse signal whose unit is millimetre (mm). The x-axis is the time whose unit is second (s).
