近年来，人们提出了许多基于移动系统的心电图监测方案。我们在这里提出了一种基于stm32f微控制器的心电移动系统，根据这些记录的临床标准要求，提供长期（几周）动态心电图监测和12导联心电记录，此外还可以在接近采集的阶段产生进一步的数字压缩。该系统在发展中国家的农村地区尤其有用，在这些地区，由于缺乏专门的医务人员，需要引入远程心脏学服务，而蜂窝网络的覆盖范围和带宽有限，需要使用有效的信号压缩系统。原型是使用一个小型架构实现的，每个样本的分辨率为16位。我们还使用了一个低噪声仪表放大器TI ADS1198，它具有一个多路复用器和一个模数转换器（16位和8通道）连接到STM32F处理器，其架构包含一个数字信号处理单元和一个浮点单元。一方面，系统的便携性允许用户将原型机放在口袋中，根据临床需要进行心电图检查，无论是在12导联控制条件下还是在动态心电图监测下。智能手机中的应用程序负责为用户提供一个友好的界面来设置系统。另一方面，患者的电子健康记录被登记在一个网络应用程序中，该应用程序反过来允许他们从手机连接到互联网，然后心电图信号通过网络服务器发送，供医生在任何方便的终端设备上进行后续和无处不在的分析。为了确定接收到的信号的质量，在以下三种场景下进行系统测试：(1)将原型机连接到患者身上，随后将信号存储；(2)将原型连接到患者身上，随后将数据传输到手机；(3)将原型连接到患者身上，通过互联网将数据传输到手机和网络上。与专家临床医生进行的额外基准测试显示了该系统提供的临床质量。所提出的心电系统是第一步，在与心电图实践的兼容性方面为移动心电监护铺平了道路，包括长期监测，12导联的可用性，以及在ECG采集的早期阶段合并信号压缩的可能性。
In recent years, a number of proposals for electrocardiogram (ECG) monitoring based on mobile systems have been delivered. We propose here an STM32F-microcontroller-based ECG mobile system providing both long-term (several weeks) Holter monitoring and 12-lead ECG recording, according to the clinical standard requirements for these kinds of recordings, which in addition can yield further digital compression at stages close to the acquisition. The system can be especially useful in rural areas of developing countries, where the lack of specialized medical personnel justifies the introduction of telecardiology services, and the limitations of coverage and bandwidth of cellular networks require the use of efficient signal compression systems. The prototype was implemented using a small architecture, with a 16-bits-per-sample resolution. We also used a low-noise instrumentation amplifier TI ADS1198, which has a multiplexer and an analog-to-digital converter (16 bits and 8 channels) connected to the STM32F processor, the architecture of which incorporates a digital signal processing unit and a floating-point unit. On the one hand, the system portability allows the user to take the prototype in her/his pocket and to perform an ECG examination, either in 12-lead controlled conditions or in Holter monitoring, according to the required clinical scenario. An app in the smartphone is responsible for giving the users a friendly interface to set up the system. On the other hand, electronic health recording of the patients are registered in a web application, which in turn allows them to connect to the Internet from their cellphones, and the ECG signals are then sent though a web server for subsequent and ubiquitous analysis by doctors at any convenient terminal device. In order to determine the quality of the received signals, system testing was performed in the three following scenarios: (1) The prototype was connected to the patient and the signals were subsequently stored; (2) the prototype was connected to the patient and the data were subsequently transferred to the cellphone; (3) the prototype was connected to the patient, and the data were transferred to the cellphone and to the web via the Internet. An additional benchmarking test with expert clinicians showed the clinical quality provided by the system. The proposed ECG system is the first step and paves the way toward mobile cardiac monitors in terms of compatibility with the electrocardiographic practice, including the long-term monitoring, the usability with 12 leads, and the possibility of incorporating signal compression at the early stages of the ECG acquisition.
