What affects pulse wave?

Pulse wave velocity (PWV) is one of the most widely used surrogates of arterial stiffness [1]. Previous studies demonstrated that PWV is associated with various factors such as age, gender, salt intake, genetic factors, blood pressure (BP), and heart rate (HR) [2, 3].

What does the pulse wave represent?

Pulse pressure wave analysis allows calculation of the speed of the pulse (PWV) and 'augmentation' of the pulse pressure in the ascending aorta (AIx), both of these measures are related to vascular stiffness, a key component of atherosclerosis.

What type of wave is a pulse?

A pulse wave or pulse train is a type of non-sinusoidal waveform that includes square waves (duty cycle of 50%) and similarly periodic but asymmetrical waves (duty cycles other than 50%).

What is the frequency of a pulse wave?

The pulse waves of humans comprise signals of multiple frequencies, with the lowest frequencies in the range of 0.8–1.7 Hz [27]. Hence, the cutoff frequency of the high-pass filter of the sensor should be less than 0.8 Hz.
