There has been an increasing interest in using cardiac indicators of self-regulation in developmental science. Many researchers are interested in unobtrusive mobile devises that are able to collect reliable cardiac data outside of the laboratory setting. Although numerous new ambulatory devices have become available over the last decade, testing these devices on children in comparison to industry gold-standard devices is rarely conducted. The current study evaluated the reliability of one of these ambulatory systems, the BodyGuard2 (FirstBeat), relative to gold-standard laboratory electrocardiogram (Biopac MP150), during active and resting conditions in 4- to 6-year-old children. The BodyGuard2 performed and produced highly similar indices of heart rate variability across resting and active conditions.

在发展科学中使用自我调节的心脏指标越来越受到关注。许多研究人员对能够在实验室环境之外收集可靠心脏数据的不显眼的移动设备感兴趣。尽管在过去十年中出现了许多新的移动设备，但与行业黄金标准设备相比，很少在儿童身上测试这些设备。当前的研究评估了其中一个动态系统 BodyGuard2 (FirstBeat) 相对于黄金标准实验室心电图 (Biopac MP150) 在 4 至 6 岁儿童活动和休息条件下的可靠性。BodyGuard2 在休息和活动条件下执行并产生高度相似的心率变异指数。
