Abstract

Background: WenXinWuYang, a novel portable Artificial Intelligence Electrocardiogram (AI-ECG) device, can detect many kinds of abnormal heart disease and perform a single-lead ECG, but its reliability and validity among pregnant women is unclear. The aim of this study was to assess the reliability and validity of heart rate, ECG measurements and diagnostic results by compared the portable device with a clinical 12-lead ECG among pregnant women.

Methods: We conducted a clinical study at a municipal-level maternal and child health care hospital. The pregnant women who visited the ECG room for ECG examination were invited to participate in this study. Each participant underwent three ECG recordings: one with conventional 12-lead ECG and two with WenXinWuYang ECG. The first WenXinWuYang ECG was recorded simultaneously with the 12-lead ECG. We collected heart rate, ECG measurements, and diagnostic results related to arrhythmias from both ECG devices. The data were then analyzed using Spearman rank correlation coefficients, consistency analyses, and Bland-Altman plots.

Results: The study included 287 ECG recordings from 99 pregnant women, with a balanced distribution across different stages of pregnancy. We observed strong to moderate correlations between the two WenXinWuYang measurements for heart rate (r = 0.847), PR interval (r = 0.728), QRS duration (r = 0.636), QT interval (r = 0.836), and QTc interval (r = 0.648), with a diagnostic consistency rate exceeding 90.0%. When compared with the 12-lead ECG, the mean differences for heart rate, PR interval, QRS duration, QT interval, and QTc interval were - 0.4 ± 3.1 bpm (r = 0.957), 14.6 ± 12.4 ms (r = 0.537), 7.0 ± 8.9 ms (r = 0.136), 2.1 ± 12.0 (r = 0.774), and 6.6 ± 16.5 (r = 0.663), respectively. Although the correlation coefficient was low in QRS duration, Bland-Altman results showed moderate to strong agreement between these intervals. Sinus rhythm recognition was fully consistent with the 12-lead ECG, with higher validity in detecting arrhythmias (sensitivity 84.2%, specificity 97.5%). Similar trends existed among different stages of pregnancy.

Conclusion: WenXinWuYang demonstrated acceptable reliability and validity in measuring heart rate, ECG measurements, and detecting arrhythmias among pregnant women.

一种新型孕妇单导联便携式心电图仪的信度和效度比较研究。
背景:WenXinWuYang是一种新型便携式人工智能心电图(AI-ECG)设备,可检测多种异常心脏疾病并进行单导联心电图,但其在孕妇中的信度和效度尚不清楚。本研究的目的是通过比较便携式设备与临床12导联心电图,评估孕妇心率、心电图测量和诊断结果的可靠性和有效性。方法:在某市级妇幼保健院进行临床研究。邀请到心电室进行心电图检查的孕妇参与本研究。每位参与者进行了三次心电图记录:一次是常规的12导联心电图,两次是温心五阳心电图。第一次温心五阳心电图与12导联心电图同时记录。我们收集了两种ECG设备的心率、心电图测量和与心律失常相关的诊断结果。然后使用Spearman秩相关系数、一致性分析和Bland-Altman图对数据进行分析。结果:该研究包括来自99名孕妇的287份心电图记录,在不同的妊娠阶段分布均衡。我们观察到温心五阳两项指标在心率(r = 0.847)、PR间期(r = 0.728)、QRS持续时间(r = 0.636)、QT间期(r = 0.836)和QTc间期(r = 0.648)之间存在强至中度相关性,诊断符合率超过90.0%。与12导联心电图比较,心率、PR间期、QRS持续时间、QT间期、QTc间期的平均差异分别为- 0.4±3.1 bpm (r = 0.957)、14.6±12.4 ms (r = 0.537)、7.0±8.9 ms (r = 0.136)、2.1±12.0 (r = 0.774)、6.6±16.5 (r = 0.663)。虽然QRS持续时间的相关系数较低,但Bland-Altman结果显示这些间隔之间存在中度到高度的一致性。窦性心律识别与12导联心电图完全一致,检测心律失常的有效性较高(敏感性84.2%,特异性97.5%)。在怀孕的不同阶段也存在类似的趋势。结论:温心五阳在孕妇心率测量、心电测量和心律失常检测中具有良好的信度和效度。
