Abstract

Background

Devices equipped with electrocardiographic (ECG) technology possess design limitations reducing their feasibility across a range of users and environments.

Purpose

This study evaluated the validity of a novel, single-limb biomedical device using single‑lead ECG technology located on the upper arm for monitoring cardiac activity in a large, diverse sample.

Methods

A cross-sectional study was conducted among 931 adults from May to September 2024 at an outpatient medical center in the United States. ECG recordings were captured on the Warfighter Monitor™ (WFM; Tiger Tech Solutions, Miami, FL). Each participant wore two ECGs simultaneously, a standard Lead-I ECG on the chest (ECG-Chest) and a WFM on the upper arm (ECG-Bicep), for 5 to 7 min. Agreement between ECG-Chest and ECG-Bicep measurements for HR and HRV were evaluated using Pearson correlations, Bland-Altman, and ANOVA.

Results

The study population was diverse in age (17–99 years), sex (53.4% male), and ethnicity (53.7% Hispanic or Latino), and comorbidities: cardiovascular (61.2%), respiratory (31.5%), cancer (20.3%), endocrine (43.4%), and neurological (32.5%) disorders. Near-perfect correlations (0.995–0.997, p < 0.0001) and negligible mean differences (−0.02 to 0.05 bpm or ms, p < 0.00001) were found between ECG-Chest and ECG-Bicep for HR and HRV metrics.

Conclusion

The near-perfect agreement in HR and HRV between ECG recordings measured at the chest and bicep, confirms the strong validity of the WFM for precise, ECG-based monitoring across a broad set of demographics. These results demonstrate the high accuracy, versatility, and feasibility of the WFM to accurately monitor HR and HRV.

战士监护仪单肢心电图技术的有效性。

背景：配备心电图（ECG）技术的设备具有设计限制，降低了其在一系列用户和环境中的可行性。目的：本研究评估了一种新型单肢生物医学装置的有效性，该装置使用位于上臂的单导联心电图技术来监测大量不同样本的心脏活动。方法：一项横断面研究于2024年5月至9月在美国一家门诊医疗中心对931名成年人进行。心电记录在Warfighter Monitor™（WFM; Tiger Tech Solutions, Miami， FL）上捕获。每个参与者同时佩戴两个心电图，一个是标准的胸部导联心电图（ECG-胸部），另一个是上臂WFM心电图（ECG-肱二头肌），持续5至7分钟。采用Pearson相关性、Bland-Altman和方差分析评估ecg -胸和ecg -二头肌测量HR和HRV的一致性。结果：研究人群在年龄（17-99岁）、性别（53.4%为男性）、种族（53.7%为西班牙裔或拉丁裔）和合并症方面存在差异：心血管疾病（61.2%）、呼吸疾病（31.5%）、癌症疾病（20.3%）、内分泌疾病（43.4%）和神经疾病（32.5%）。结论：在胸部和二头肌测量的心电图记录之间的HR和HRV接近完美的一致性，证实了WFM在广泛的人口统计学中精确的、基于ECG的监测的强大有效性。这些结果证明了WFM准确监测HR和HRV的准确性、通用性和可行性。
