Having mobile devices that provide patients with the ability to record and monitor the electrical activity of their heart enhances patient self-care and the early detection of irregular heartbeat (cardiac arrhythmia), yet few such devices exist in Vietnam. Challenges exist for introducing mobile electrocardiography (ECG) monitoring devices in Vietnam, including patient accessibility and affordability. A low-cost mobile ECG monitoring device designed and developed in Vietnam, which allows patients to easily measure their heart's electrical activity and navigate recordings, may be a solution.
The aim of this project is to assess the usability of the MD-Link system, a newly developed mobile handheld 1-lead ECG device, in detecting patients with irregular heartbeat. We will compare its outputs to the standard printed outputs of a 12-lead electrocardiogram generated by the Nihon Kohden Cardiofax S Electrocardiograph Model ECG-1250K.
We will conduct a cross-sectional study in two stages, including the measurement of ECG signals of patients using the MD-Link and the Nihon Kohden Cardiofax S and analysis of the selected standard outputs collected from the ECG recordings of the MD-Link and the Nihon Kohden Cardiofax S. The MD-Link consists of (1) a mobile device (eg, a smartphone); (2) a lead wire with 2 disposable electrodes; and (3) an easy-to-use mobile app interface enabling the upload and accurate display of ECG recordings to patients and their clinicians. Our research team, consisting of members from Dartmouth College; the Institute of Health, Population and Development; Hanoi University of Science and Technology; and physicians and nurses from Thanh Chan Clinic, will assist in carrying out this project.
We will proceed with a publication plan that includes a project report and, ultimately, articles for peer-reviewed journals. We also hope to disseminate our work at relevant conferences to provide more coverage and exposure to the MD-Link mobile device. Recruitment and data collection were completed in January 2018. Data analysis started in February 2018 and is ongoing. Results are expected mid-2019.
At the end of this project, we will have developed and tested the MD-Link, a low-cost mobile ECG monitoring device, with some supportive comparisons to standard ECG devices commonly used in heart clinics or hospitals in Vietnam. Our long-term goal is for the MD-Link to be easily accessible, affordable, and to fit into a patient's daily routine, thus improving the care and treatment of patients with cardiovascular diseases (CVDs).

拥有能让患者记录和监测心脏电活动的移动设备可增强患者自我护理能力并有助于早期发现心律失常，但越南此类设备很少。在越南引入移动心电图（ECG）监测设备存在诸多挑战，包括患者可及性和可负担性。在越南设计和开发的一种低成本移动ECG监测设备，能让患者轻松测量心脏电活动并查看记录，可能是一个解决方案。
本项目旨在评估新开发的移动手持单导联ECG设备MD-Link系统在检测心律失常患者方面的可用性。我们将把它的输出结果与日本光电Cardiofax S心电图机型号ECG-1250K生成的12导联心电图的标准打印输出结果进行比较。
我们将分两个阶段进行横断面研究，包括使用MD-Link和日本光电Cardiofax S测量患者的ECG信号，以及分析从MD-Link和日本光电Cardiofax S的ECG记录中收集的选定标准输出。MD-Link由（1）一个移动设备（如智能手机）；（2）一根带有2个一次性电极的导联线；以及（3）一个易于使用的移动应用程序界面组成，该界面能将ECG记录上传并准确显示给患者及其临床医生。我们的研究团队由达特茅斯学院、健康、人口与发展研究所、河内科技大学的成员以及清禅诊所的医生和护士组成，将协助开展本项目。
我们将推进一个出版计划，包括一份项目报告，最终还会撰写同行评审期刊文章。我们还希望在相关会议上传播我们的工作，以便更广泛地介绍MD-Link移动设备。招募和数据收集已于2018年1月完成。数据分析于2018年2月开始，目前仍在进行中。预计2019年年中得出结果。
在本项目结束时，我们将开发并测试MD-Link，一种低成本移动ECG监测设备，并与越南心脏诊所或医院常用的标准ECG设备进行一些支持性比较。我们的长期目标是使MD-Link易于获取、价格可承受，并融入患者的日常生活，从而改善心血管疾病（CVD）患者的护理和治疗。
