Identifying Coronary Artery Lesions by Feature Analysis of Radial Pulse Wave: A Case-Control Study

Table 1

Physiological significances of time-domain features of pulse wave.

No.	Parameters	Physiological significance
1	H2/H1	It reflects the compliance and peripheral resistance of the vascular wall.
2	H3/H1	It reflects the compliance and peripheral resistance of the vascular wall.
3	H4/H1	It reflects peripheral resistance.
4	H5/H1	It reflects the compliance of the aorta and the function of the aortic valve.
5	T(s)	It reflects the pulse wave period.
6	W1(s)	It reflects the duration of high arterial pressure.
7	W2(s)	The duration of maintaining high intravascular pressure.
8	T1/T	It reflects the ejection function of the heart.
9	T1/T4	It reflects the rapid ejection of the heart.
