Figure 2 Examples of ECG traces recorded with smart textiles (red) and Ag/AgCl (blue) electrodes. In the Ag/AgCl-based recording, high-amplitude peaks are shown in the trace, which are generated by MAs and can be confused with the R peaks. The real R peaks collected with Ag/AgCl electrodes have smaller amplitudes.

Figure 3 The number of MAs over time recorded for each of the 7 horses. In the histograms, the reported values relate to the signal sample. A signal sampled at 250 Hz has 250 samples/s. Given that an artifact is identified with a piece of altered signal, the number of the samples included in each artifact (y axis) for each bin (x axis) has been counted.
