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 comma-separated value (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.
