Abstract

Several studies have highlighted the need of reliable markers to determine cardiac health. One of the most promising markers is the heart rate variability (HRV). However, artifacts, such as ectopic beats, have to be corrected before HRV parameters can be reliably used. This paper reviews several recently established models that are used for ectopic beat correction, with an emphasis on execution time and memory requirements. In general, physiologic models require far more execu-tion time, while memory demand is compareable to simpler algorithms. Moreover, physiologic models result in better corrections, compared to simpler methods. Therefore, we conclude that physiologic models are prefferable since the execution time is low enough to use all models in an online approach.
