Cardiovascular diseases and, in particular, diseases related to arrhythmias are a problem that affects a significant percentage of the population, being one of the major causes of death in Europe. New advances in the fields of PDAs, mobile phones, wireless communications and vital parameter sensors have permitted the development of revolutionary medical monitoring systems, which strikingly improve the lifestyle of patients. However, not all those monitoring systems provide patients with real assistance - anywhere and at any time. We have developed a system that goes a step further than the previous approaches, being designed to capture, record and, as a distinctive feature, locally analyze the ECG signals in a PDA carried by the patient. In that sense, the system has a decision support module based on decision tree methods that can detect, with high precision, any arrhythmias that the user may be suffering. Alarms can then be activated in time to alert a medical center in order to provide the proper medical assistance. One of our aims when building the system has been to optimize limited and expensive resources like PDA memory size and wireless communication costs. Moreover, accessibility is also an important feature of the system that has been achieved by the development of web services to query the data computed in the PDA. In this way, authorized personnel (physicians and relatives) can easily obtain access to that data.
心血管疾病，尤其是与心律失常相关的疾病，是一个影响相当大比例人口的问题，是欧洲主要死因之一。掌上电脑（PDA）、手机、无线通信和生命参数传感器领域的新进展使得革命性的医疗监测系统得以开发，显著改善了患者的生活方式。然而，并非所有这些监测系统都能随时随地为患者提供真正的帮助。我们开发了一种系统，它比以前的方法更进一步，旨在捕获、记录并作为其独特功能在患者携带的PDA中对心电图信号进行本地分析。从这个意义上说，该系统有一个基于决策树方法的决策支持模块，能够高精度地检测用户可能患有的任何心律失常。然后可以及时激活警报以提醒医疗中心，以便提供适当的医疗援助。我们构建该系统的目标之一是优化诸如PDA内存大小和无线通信成本等有限且昂贵的资源。此外，通过开发用于查询PDA中计算数据的网络服务，可访问性也是该系统的一个重要特性。通过这种方式，授权人员（医生和亲属）可以轻松获取该数据。
