【摘要】 常规的心电图通常是病人处在静卧(非活动状态)下的一种短时间(几秒至几十秒的心电记录,很难捕捉到心脏疾病病人的心律失常数据。统计已经表明:只有通过长时间对心电图的连续观察处在正常生活或运动状态下的心电信息,才有可能获得病人心律失常(例如室行性早搏)的早期和潜在心电信息。通常将病人处在活动条件下长期记录的心电图称为动态心电图。本论文将嵌入式设计的软硬件协同设计方法应用于动态心电记录器的设计全过程。在传统心电采集和记录器的基础上,应用S3C44B0X作为核心处理器,为系统提供了很强的处理能力和升级空间。软件应用了实时嵌入式操作系统,克服了传统单任务前后台软件设计的弊端,有助于建立功能强大、结构复杂的大系统,提高系统的可靠性和实时性,降低了软件设计的难度。论文对系统的硬件架构和软件架构设计以及心电信号处理等进行了详细的描述,并对系统运行情况给出了详细记录和分析。更多还原

【Abstract】 Electrocardiogram monitor is a precise electronic-medical equipment in modern medical research and clinic diagnosis. The electrocardiogram monitoring system mainly consisted of the function of collecting, analyzing and diagnosing heart-electricity signals is widely used, which records the signals of heart-electricity impulse to check out the condition of a patient’s heart, to prevent or diagnosis heart attack. It is of great use and meaning in protecting people’s physical health and improving people’s life quality.The very circuit in charge of collecting and processing heart-electricity signals is the main part of a electrocardiogram monitor, which is a monitoring circuit that processes both analog and digital signals. The former of that monitoring circuit is a heart-electricity collecting system based on analog technique, behind of which is a wave-showing circuit totally based on digital signal processing. The structure of this monitoring circuit is clear and easy to accomplish.In the former part about theory concerns, we introduce the definition and character of bioelectricity signals, the restrict of bioelectricity signal detecting, the principle of heart-electricity signals producing and the character of heart-electricity signals, so that we could get full awareness of the differences between heart-electricity signals and other更多还原
