PWs

PWs

A directory containing PWs at the most common measurement sites in the three different formats.

mat

This subdirectory contains PWs in Matlab ® format. The PWs are provided in a separate file for each measurement site (defined here). Each file contains a structure called PWs, which contains:

contains the following fields.

Field	Contents
fs	Wave sampling frequency, measured in Hz
P_#####	A cell containing arterial blood pressure (P) waves, measured in mmHg, for each virtual subject
U_#####	A cell containing arterial blood flow velocity (U) waves, measured in m/s, for each virtual subject
A_#####	A cell containing arterial luminal area (A) waves, measured in m3, for each virtual subject
PPG_#####	A cell containing Photoplethysmogram (PPG) waves for each virtual subject (arbitrary units)
onset_times	The onset times of each of the PWs, measured in secs the onset time at the aortic root.

csv

This subdirectory contains PWs in CSV format. The PWs are provided in a separate file for each measurement site (defined here) and for each of the four pulse wave types (P, U, A and PPG).

Each file contains the PWs sampled at 500Hz. The PWs for each virtual subject are presented in separate rows. Each column is a sample.

WFDB

This subdirectory contains PWs in WaveForm DataBase format (as used by PhysioNet).

Each .dat file contains all the PWs at common measurement sites for a particular virtual subject. The contents of the .dat files are summarised in the corresponding .hea files.
