Howell, L. and Porr, B. (2018) High precision ECG Database with annotated R peaks, recorded and filmed under realistic conditions. [Data Collection]

Not all data is available to download from this page. Usually this is because the dataset is too large or it is restricted in some way.

Collection description

This database contains ECGs from 25 subjects. Each subject was recorded performing 5 different tasks for two minutes:
•sitting
•a maths test on a tablet
•walking on a treadmill
•running on a treadmill
•using a hand bike

The following channels were recorded with two Attys running synchronously:
•Einthoven II and III with standard cables and the amplifier worn around the waist
•Exercise cheststrap ECG which resembles approximtely V2-V1 with the ECG amplifier directly mounted on the strap
•Acceleration in X/Y/Z whith the sensor mounted directly on the chest strap

The cheststrap ECG allowed R peak detection even while jogging at a very high precision (+/- one sample). The sampling rate was 250Hz at a resolution of 24 bits. The database contains the unfiltered, DC-coupled signals as originally recorded. In order to be able to link the ECG artefacts to the behaviour of the subject all but one subject gave permission to be filmed and the videos are also part of the database.
