由于固定基础设施成本高昂，目前的有线远程医疗系统在群岛发展中国家实施时遇到困难。在这项研究中，我们设计了Lifelink，一个移动实时远程监测和诊断设备，通过手机来指挥和控制远程医疗设备。整个过程是基于电话的，有效地将非现场医疗专家从固定的监控控制台中解放出来，并使该系统具有增加参与咨询人数的潜力。使用去趋势波动技术分析心电(ECG)读数，并使用无辅助K均值聚类算法将其分类为病理病例。我们分析了30批来自心脏病患者(20名男性，10名女性，平均年龄46.7岁)的2小时心电信号，这些患者都有预先诊断的病理。该方法成功地将30名没有用户干预的受试者分为以下情况：正常(86.7%的准确率)、充血性心力衰竭(86.7%)和房颤(80.0%)。移动监测和波动分析的协同作用提供了一个强大的平台，可以接触到有线通信结构较差或根本不存在的偏远、服务不足的社区。这很可能是开发新的流动诊断和预后措施的关键。
Current wired telemedicine systems encounter difficulties when implemented in archipelagic developing countries because of the high cost of fixed infrastructure. In this research, we devised Lifelink, a mobile real-time telemonitoring and diagnostic facility to command and control remote medical devices through mobile phones. The whole process is phone-based, effectively freeing off-site medical specialists from stationary monitoring consoles and endowing the system with the potential to increase the number participating consultants. The electrocardiogram (ECG) readings are analyzed using a detrended fluctuation technique and classified into pathological cases using an unassisted K-means clustering algorithm. We analyzed 30 batches of 2-hour ECG signals taken from cardiac patients (20 males, 10 females, mean age 46.7 years) with pre-diagnosed pathologies. The method successfully categorized the 30 subjects without user intervention into the following cases: normal (at 86.7% accuracy), congestive heart failure (86.7%), and atrial fibrillation (80.0%). The synergy of mobile monitoring and fluctuation analysis presents a powerful platform to reach remote, underserved communities with poor or nonexistent wired communication structures. It is likely to be essential in the development of new mobile diagnostic and prognostic measures.
