pwdb_data_w_######_paths.mat

a set of Matlab ® files containing pulse waves every 4cm from the aortic root to: (i) the finger; (ii) the foot; (iii) the brain; and (iv) the right subclavian artery.

This page provides details of the contents of these files, which are called:

• pwdb_data_w_aorta_brain_path.mat
• pwdb_data_w_aorta_finger_path.mat
• pwdb_data_w_aorta_foot_path_a.mat
• pwdb_data_w_aorta_foot_path_p.mat
• pwdb_data_w_aorta_foot_path_u.mat
• pwdb_data_w_aorta_rsubclavian_path.mat

Each file contains a single structure called data, with three fields:

• data.config: Details of the model configuration used for each virtual subject
• data.path_waves: The simulated PWs along the specified arterial path for each virtual subject
• data.haemods Haemodynamic parameters extracted from PWs for each virtual subject

The data.config and data.haemods fields are identical to those in the pwdb_data.mat file, as described here. The contents of the data.path_waves structure are now described.

data.path_waves

This structure contains pulse waves measured along one of the following paths:

• aorta_finger: The arterial path from the aortic root to the end of the left digital artery (finger).
• aorta_foot: The arterial path from the aortic root to the end of the left anterior tibial artery (ankle).
• aorta_brain: The arterial path from the aortic root to the end of the left anterior tibial artery (ankle).
• aorta_r_subclavian: The arterial path from the aortic root to the end of the right subclavian artery.

The pulse waves for each path are provided in a structure. This structure contains a cell array for each type of pulse wave, for each subject:

• P: pressure pulse wave (mmHg)
• U: flow velocity pulse wave (m/s)
• A: luminal area pulse wave (m^2)

An exception to this is the aorta_foot path waves, which are provided in three separate files (for each of the pressure, P, flow velocity, U, and luminal area, A, pulse wave types).

The cell arrays contain the pulse waves at the measurement sites along the arterial path. The following additional information is provided, corresponding to each individual pulse wave:

• dist: distance of measurement site from aortic root (m)
• artery: name of the artery
• segment_no: the number of the segment containing this measurement site
• artery_dist: the distance along this artery (m)
• onset_time: the pulse onset time (s)
