Abstract
The use of heart rate measures in research requires accurate detection and timing of beat-to-beat values. Numerous technologies are available to researchers; however, benchmarking of a specific apparatus is seldom conducted. Since heart rate variability provides a portal to the neural regulation of the heart, accurate detection and timing of beat-to-beat values is essential to both basic physiological research and the clinical application of heart rate variability measures. The current study evaluated the accuracy of an ambulatory system, the LifeShirt (Vivometrics), relative to a standard laboratory-based heart rate monitoring equipment (Biopac), during baseline and exercise conditions. LifeShirt performed equivalently to the Biopac during both conditions, experienced few errors of detection, generated similar times between sequential heart periods, and produced similar summary indices of heart rate and heart rate variability.
摘要
在研究中使用心率测量需要精确检测逐搏值并记录其时间。研究人员可利用多种技术；然而，很少对特定仪器进行基准测试。由于心率变异性为心脏的神经调节提供了一个窗口，准确检测逐搏值并记录其时间对于基础生理学研究以及心率变异性测量的临床应用都至关重要。本研究评估了一种动态监测系统LifeShirt（Vivometrics公司）相对于基于标准实验室的心率监测设备（Biopac）在基线和运动条件下的准确性。在两种条件下，LifeShirt的表现与Biopac相当，检测误差少，连续心动周期之间的时间相似，并且产生的心率和心率变异性汇总指标也相似。
