【摘要】：本文介绍了一套多功能无线心电监护系统的设计与实现，该系统实现了EASI十二导联心电动态监护和常规十二导联心电检测两种模式之间的切换，可以应用于不同的临床场合。整个多功能无线心电监护系统采用了全数字化和模块化的思想进行设计，选用CPLD（Complex Programmable Logic Device）作为主控器，实现了多路心电数据的同步采集。该系统采用无线传输模式，病患可以在非静态下实现EASI十二导联心电动态监护和常规十二导联心电检测。无线模块采用的是PTR6000A，其功能强大、集成度高，降低了系统的功耗。无线接收部分与PC机之间的接口电路中，我们采用USB2.0串行接口技术实现了心电数据的高速传输。基于PC机的中央监护软件采用了多线程技术来实现实时数据读取和实时数据处理。该系统的主要特点是一机多用，，既可用于动态心电监护，也可用于常规心电检测。其次，在动态心电监护模式下，通过同步采集标准十二导联数据和EASI三导联数据实现了EASI衍生十二导联转换系数的个体化校正，校正后仅仅使用五个电极就能提供丰富而准确的心电信息，非常适用于需要进行长程心电监护的病患。最后，我们对系统进行了验证。个体化校正后EASI衍生十二导联与常规十二导联的符合率得到了很大的提高，监测结果更加准确、可靠。
[Abstract]:This paper introduces the design and implementation of a multifunctional wireless ECG monitoring system. The system realizes the switching between EASI 12 lead ECG dynamic monitoring mode and conventional 12 lead ECG monitoring mode. It can be used in different clinical situations. The whole multifunctional wireless ECG monitoring system is designed with the idea of full digitization and modularization, and CPLD(Complex Programmable Logic device is chosen as the main controller to realize the synchronous acquisition of multi-channel ECG data. The system adopts wireless transmission mode. Patients can realize EASI 12 lead ECG dynamic monitoring and conventional lead 12 ECG monitoring under non-static condition. The wireless module uses PTR6000A, which is powerful and highly integrated. The power consumption of the system is reduced. In the interface circuit between the wireless receiving part and the PC, We adopt USB2.0 serial interface technology to realize the high-speed transmission of ECG data, and the central monitoring software based on PC adopts multi-thread technology to realize real-time data reading and real-time data processing. The main feature of this system is that it can be used in both dynamic ECG monitoring and conventional ECG monitoring. Secondly, in dynamic ECG monitoring mode, The individualized correction of EASI derivative 12 lead conversion coefficient is realized by synchronously collecting standard 12 lead data and EASI three lead data. Using only five electrodes after correction can provide rich and accurate ECG information. Very suitable for patients who need long-range ECG monitoring. Finally, we verify the system. The coincidence rate of EASI derived 12 leads and conventional 12 leads has been greatly improved after individualized correction, and the monitoring results are more accurate and reliable.
