Short duration ECG signals are recorded from a healthy 25-year-old male performing different physical activities to study the effect of motion artifacts on ECG signals and their sparsity.
For each measurement, 4 pairs of electrodes built into a single patch are placed on the subject. The electrodes are arranged at 45-degree offsets as shown below:
![[Positions of electrodes in the patch]](patch_electrodes.jpg)
The patch itself is also placed at multiple orientations relative to the body:

Each recording contains four signals (ECG 1
to ECG 4
) corresponding to the four pairs of electrodes.
Recording information:
- Sampling rate: 500 Hz
- Resolution: 16 bits
- An analogue gain of 100 is applied to the raw ECG recordings before ADC.
- The 2-digit number before the last letter shows the offset of the whole electrode patch in degrees.
- The last letter of each record name corresponds to the type of physical activity as below:
- s = standing
- w = walking
- j = single jump
