摘要

目的：本研究旨在评估便携式12导联心电图（ECG）设备在心脏病患者中的准确性和可靠性。材料和方法：这项单中心、前瞻性、盲法研究于2023年9月至10月从某三甲医院心脏中心招募了62例患者。在对每位患者进行的顺序试验中，将使用便携式12导联仪（Weheal， CN）获得的心电图记录的心率（HR）、PR、QT、QTc和QRS间期与常规12导联心电图记录的心电图进行比较。3名盲法电生理学家分批读取心电参数。采用双尾配对t检验比较连续变量。通过Bland-Altman图评估一致性。结果：纳入62例患者。便携式12导联心电图记录的HR、QT、QTc和QRS间期与常规心电图记录基本相同。Bland-Altman分析显示这些值没有显著差异，表明2个测量值之间存在合适的一致性。便携式组的PR间期为176.89±29.53 ms，标准组的PR间期为161.56±17.78 ms，差异有统计学意义(p)。结论：使用便携式12导联仪（Weheal， CN）获得的心电图记录可以准确评估HR、PR、QT、QTc和QRS。考虑到它的简单性，这种方法比传统的心电图有优势，可以为医院外的患者提供评估的替代方法。如何提高患者对便携式心电机的接受程度还有待进一步研究。

Clinical value of portable 12‐lead electrocardiography devices in patients with heart disease: A validation study

Objective

The present study was conducted to assess the accuracy and reliability of portable 12‑lead electrocardiography (ECG) devices in patients with heart disease.

Materials and methods

This single-center, prospective, blinded study enrolled 62 patients between September and October 2023 from the Heart Center of a Class III hospital. In sequential tests on each patient, heart rate (HR) and the PR, QT, QTc and QRS intervals of ECG recordings obtained with a portable 12‑lead device (Weheal, CN) were compared with those obtained via conventional 12‑lead ECG. ECG parameters were read in batches by 3 blinded electrophysiologists. Two-tailed paired t-tests were used to compare the continuous variables. Agreement was evaluated via Bland–Altman plots.

Results

Sixty-two patients were included. HR and the QT, QTc and QRS intervals from the portable 12‑lead electrocardiogram recordings were essentially the same as those obtained via conventional ECG. Bland–Altman analysis revealed no significant differences in these values, indicating suitable agreement between the 2 measurements. The PR interval was 176.89 ± 29.53 ms in the portable group and 161.56 ± 17.78 ms in the standard group, which was statistically (p < 0.001) but not clinically significant.

Conclusions

ECG recordings obtained with a portable 12‑lead device (Weheal, CN) allow for accurate HR, PR, QT, QTc and QRS assessments. Considering its simplicity, this approach has advantages over conventional ECG and can provide an alternative for evaluating patients outside the hospital. How to improve patients' acceptance of portable ECG machines still needs further research.
