At UK Biobank, we collect heart function data by conducting an electrocardiogram (ECG) on volunteers, providing information on both heart rate and rhythm. The two types of ECG data currently available to researchers are resting state and exercise ECG measures, which have been collected from 2006 until 2024. These two ECG measurements were collected on different instances, meaning that whilst 90k participants had an exercise ECG taken from 2006 to 2013, another 90k participants (and climbing) had an at rest ECG taken from 2014 to 2024.
At rest, measurements were taken using a standard 12-lead ECG (GE Cardiosoft ver. 6) which places electrodes on the chest, forearms and calves. Data was collected over a 10 second interval using an automated system, where clinicians did not check for any incidental clinical findings.
The exercise ECG involved the use of a 4-lead ECG (CAM-USB 6.5, Cardiosoft ver. 6.51) which places electrodes on the participant’s cubital fossae and wrists during a stationary cycling exercise. The measurement lasted for a longer 7 minute and 15 second interval, whereby a pre-test took 15 seconds, the activity itself took 6 minutes, and 1 minute was collected during recovery. The exported format for this data is a raw XML file, without any additional pre-processing.
