Overview

This database of arterial pulse waves is designed to be representative of a young, healthy subject at different levels of mental stress. It contains simulated pulse waves at common measurement sites. Simulations were conducted for different cardiovascular properties based on the haemodynamic changes with stress reported in the literature.

Details

The database contains arterial flow rate (Q), luminal area (A), pressure (P) and photoplethysmogram (PPG) pulse waves at a range of measurement sites, including: (i) aortic root; (ii) carotid artery; (iii) brachial artery; (iv) radial artery; (v) finger; (vi) femoral artery; and (vii) temporal artery. It is provided in Matlab ® format.
