Abstract
In this work, the performance of 5 methods to calculate the ECG derived respiration is compared when applied to ECG signals with irregular beats. The results suggest that approaches based on the R-peaks amplitude and the difference between the R and S waves are more stable when the number of irregular beats increases to more than 2. In addition, the approach based on Kernel PCA is the most affected by ectopic beats due to its sensitivity to outliers.
