pwdb_haemod_params.csv

This spreadsheet contains haemodynamic parameters measured from each subject's pulse waves.

The haemodynamic parameters provided for each subject are:

Abbreviation	Parameter
age	Age, in years
HR	Heart rate (HR), in beats per minute (bpm)
SV	Stroke volume (SV), in millilitres (ml)
CO	Cardiac output (CO), in litres per minute (l/min)
LVET	Left ventricular ejection time (LVET), in milliseconds (ms)
dp/dt	Maximum value of first derivative of the aortic root pressure wave, in mmHg per second (mmHg/s)
PFT	time of peak flow at aortic root, in milliseconds (ms)
RFV	reverse flow volume at aortic root, in millilitres (ml)
SBP	systolic blood pressure, in mmHg
DBP	diastolic blood pressure, in mmHg
MBP	mean blood pressure, in mmHg
PP	pulse pressure, in mmHg
PP_amp	pulse pressure amplification, a ratio of brachial to aortic PP
AP	augmentation pressure at the carotid artery, in mmHg
AIx	augmentation index at the carotid artery, %
Tr	time to reflected wave at carotid artery, in ms
PWV_a	pulse wave velocity (m/s) measured between the aortic root and iliac bifurcation
PWV_cf	pulse wave velocity (m/s) measured between the carotid and femoral arteries
PWV_br	pulse wave velocity (m/s) measured between the brachial and radial arteries
PWV_fa	pulse wave velocity (m/s) measured between the femoral and anterior tibial (ankle) arteries
dia_asca	ascending aorta diameter (mm)
dia_dta	descending thoracic aorta diameter (mm)
dia_abda	abdominal aorta diameter (mm)
dia_car	carotid diameter (mm)
len	length of proximal aorta (mm)
drop fin	MBP drop from aortic root to digital artery, mmHg
drop ankle	MBP drop from aortic root to anterior tibial artery, mmHg
SVR	systemic vascular resistance (10^6 Pa s / m3)

Note that some fields are followed by an abbreviation indicating arterial site:

• a - aortic root
• b - brachial artery
• f - finger
