Key result
The low-cost BITalino ECG system demonstrated excellent agreement (>80%) with the medical-grade BrainAmp-ExG system for all but one parameter in psychophysiological experiments.
Why the study?
The reliability of low-cost mobile systems for recording ECG data is mostly unknown, raising questions about data quality and parameter validity.
Does the low-cost BITalino ECG toolkit provide equivalent ECG parameter extraction compared to an established medical-grade system (BrainAmp-ExG) in participants undergoing psychophysiological experiments?
Population
Participants watching pleasant and unpleasant pictures of the International Affective Picture System
Comparison
BITalino toolkit vs established medical-grade ECG system (BrainAmp-ExG)
Design
Simultaneous ECG recording comparative validation study

Low-cost ECG systems need prospective validation before clinical use; leaves open reliability for physiological research.
Observational
Does the low-cost BITalino ECG toolkit provide equivalent ECG parameter extraction compared to an established medical-grade system (BrainAmp-ExG) in participants undergoing psychophysiological experiments?
Effect estimate: >80% agreement
The low-cost BITalino ECG system provides equivalent data quality to a medical-grade system for stationary psychophysiological research.
Wagner et al. (2021) reported an observational. BITalino toolkit vs. BrainAmp-ExG was evaluated on Agreement of common ECG parameters (>80% agreement). The low-cost BITalino ECG system demonstrated excellent agreement (>80%) with the medical-grade BrainAmp-ExG system for all but one parameter in psychophysiological experiments.
