Few comparative studies have evaluated wearable single-lead electrocardiogram (ECG) devices and standard multi-lead ECG devices during exercise testing. This study aimed to validate the accuracy of a wearable single-lead ECG monitor for recording heart rate (HR) metrics during graded exercise tests (GXTs).
A cohort of 50 patients at a tertiary hospital underwent GXT while simultaneously being equipped with wearable single- and conventional multi-lead ECGs. The concordance between these modalities was quantified using the intraclass correlation coefficient and Bland-Altman plot analysis.
The minimum and average HR readings between the devices were generally consistent. Parameters such as ventricular ectopic beats and supraventricular ectopic beats showed strong agreement. However, the agreement for the Total QRS and Maximum RR was not sufficient. HR measurements across different stages of the exercise test showed sufficient agreement. Although not statistically significant, the standard multi-lead ECG devices exhibited higher noise levels compared to the wearable single-lead ECG devices.
Wearable single-lead ECG devices can reliably monitor HR and detect abnormal beats across a spectrum of exercise intensities, offering a viable alternative to traditional multi-lead systems.
在运动测试中，很少有比较研究评估可穿戴单导联心电图（ECG）设备和标准多导联 ECG 设备。本研究旨在验证可穿戴单导联 ECG 监测器在分级运动测试（GXT）期间记录心率（HR）指标的准确性。
一家三级医院的 50 名患者在同时配备可穿戴单导联和传统多导联 ECG 设备的情况下进行 GXT。使用组内相关系数和 Bland-Altman 图分析来量化这些模式之间的一致性。
设备之间的最小和平均 HR 读数通常是一致的。室性早搏和房性早搏等参数显示出很强的一致性。然而，对于总 QRS 和最大 RR 的一致性不够。运动测试的不同阶段的 HR 测量显示出足够的一致性。虽然没有统计学意义，但与可穿戴单导联 ECG 设备相比，标准多导联 ECG 设备显示出更高的噪声水平。
可穿戴单导联 ECG 设备可以可靠地监测 HR 并在一系列运动强度下检测异常搏动，为传统多导联系统提供了可行的替代方案。
