Abstract
This study tries to understand the consensus between modern alternative heart rate monitors and our golden standard TMSI REFA. Demonstrating if the alternative monitors are able to measure valid Heart rate (HR) and Heart rate variability (HRV), also referred to as inter-beat intervals (IBI). Wired ambulatory devices measuring with the electrocardiogram (ECG), like the TMSI REFA, are traditionally used in research settings or clinical practice. This study investigates if these wireless devices are reliable to use in these settings. We made use of the Polar H10, a chest-worn ECG monitor, and the Empatica E4, a wrist-worn watch that measures through a photoplethysmography (PPG) sensor. A sample of 28 first-year psychology students participated in an approximately 30-minute laboratory experiment. The participants were instructed to complete a variety of mental tasks (normal color Stroop task, emotional Stroop task) and physical tasks (sitting, standing). The tasks intend to elicit psychological and physical arousal, which is supposed to be detected by our devices. We found a positive correlation only between the Polar H10 and the TMSI (r = 0.94). We concluded that only the Polar H10 monitor is feasible to use in research settings since it was able to obtain the same mean IBI values as the TMSI REFA. Due to vulnerability to movement artefacts by the Empatica E4, there were too many data inconsistencies, making it unreliable to use. Further research is needed to find reproducibility between the EE4 and TMSI REFA.
