Noises and interruption during ECG monitoring
The electromyographic noise, the electrode motion artifacts, and the
temporary interruption of ECG signals were observed (Figure
6A ). The median percentage of the
total duration of noise signals and temporary interruption during the
whole monitoring duration was 0.9% (range 0.1–4.5%). Figure
6B shows the relationship between the monitoring duration and the
percentage of the noises/interruption of the monitoring. The monitoring
duration did not have a significant correlation with the duration of the
noises and the ECG signal interruption.
