ecg-age

Twelve lead resting electrocardiograms with the age of the person they were recorded from, drawn from PTB-XL and repackaged one record per file.

Every record is ten seconds at 500 Hz. Each .npz holds exactly three arrays and nothing else:

—signal, float32 of shape (12, 5000), the lead voltages in millivolts
—fs, int64, the sampling rate, always 500
—lead_names, the twelve leads in order: I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6

No other field of the source database travels with the signals. There is no sex, no diagnostic statement, no device, no recording date and no PTB-XL identifier in any file.

Layout

data/heldout/rec-0000.npz .. rec-2009.npz   2010 records, ages withheld
data/train/train-0000.npz .. train-5999.npz 6000 records
data/train/ages.csv                         id,age in whole years for data/train only

Ages are withheld for `data/heldout`. No age file is published for that folder, here or anywhere else. The 2010 held out records are drawn with a flat age distribution, 134 records in each five year band from 18 to 89, so the young are as numerous as the old. The 6000 training records keep the natural age distribution of the source database. One record per person throughout, and no person appears in both folders.
