Abstract

BACKGROUND AND OBJECTIVE

The reliability of low-cost mobile systems for recording Electrocardiographic (ECG) data is mostly unknown, posing questions regarding the quality of the recorded data and the validity of the extracted physiological parameters. The present study compared the BITalino toolkit with an established medical-grade ECG system (BrainAmp-ExG).

METHODS

Participants underwent simultaneous ECG recordings with the two instruments while watching pleasant and unpleasant pictures of the "International Affective Picture System" (IAPS). Common ECG parameters were extracted and compared between the two systems. The Intraclass Correlation Coefficients (ICCs) and the Bland-Altman Limits of Agreement (LoA) method served as criteria for measurement agreement.

RESULTS

All but one parameter showed an excellent agreement (>80%) between both devices in the ICC analysis. No criteria for Bland-Altman LoA and bias were found in the literature regarding ECG parameters.

CONCLUSION

The results of the ICC and Bland-Altman methods demonstrate that the BITalino system can be considered as an equivalent recording device for stationary ECG recordings in psychophysiological experiments.

摘要

背景与目的

目前，关于低成本移动系统记录心电图（ECG）数据的可靠性还知之甚少，这使得人们对记录数据的质量和提取的生理参数的有效性产生了疑问。本研究比较了 BITalino 工具包与一种已建立的医疗级 ECG 系统（BrainAmp-ExG）。

方法

参与者在观看“国际情感图片系统”（IAPS）的愉快和不愉快图片时，同时使用两种仪器进行心电图记录。从两种系统中提取常见的心电图参数并进行比较。组内相关系数（ICC）和 Bland-Altman 协议界限（LoA）方法是测量一致性的标准。

结果

在 ICC 分析中，除了一个参数外，两种设备的所有参数之间都显示出极好的一致性（>80%）。关于心电图参数，文献中没有 Bland-Altman LoA 和偏差的标准。

结论

ICC 和 Bland-Altman 方法的结果表明，BITalino 系统可被视为心理生理实验中进行固定心电图记录的等效记录设备。
