基于Matlab的心电信号分析与处理摘要： 本课题设计了一个简单的心电信号分析系统。直接采纳 Matlab 语言编程对输入的原始心电信号进行处理，并通过 matlab 语言编程设计对其进行时域和频域的波形频谱分析，根据具体设计要求完成系统的程序编写、调试及功能测试,得 出 一 定 的 结 论 。 (This topic has designed a simple ECG analysis system. Direct use of Matlab programming language original ECG signal input is processed, and its waveform spectrum analysis of the time domain and frequency domain matlab language programming through design, prepared in accordance with specific design requirements to complete the system of procedures, debugging and functional testing, too a certain conclusion.) 关键字：matlab、心电信号、滤波一、课题目的及意义心电信号是人类最早讨论并应用于医学临床的生物信号之一，它比其它生物电信号更易于检测，并且具有较直观的规律性，因而心电图分析技术促进了医学的进展。然而，心电图自动诊断还未广泛应用于临床，从国内外的心电图机检测分析来看，自动分析精度还达不到可以替代医生的水平，仅可以为临床医生提供辅助信息。其主要原因是心电波形的识别不准，并且心电图诊断标准不统一。因此，探究新的方法以提高波形识别的准确率，寻找适合计算机实现又具诊断价值的诊断标准，是改进心电图自动诊断效果，扩大其应用范围的根本途径。如何把心电信号的特征更加精确的提取出来进行自动分析，推断出其异常的类型成了亟待解决的焦点问题。本课题通过 matlab 语言编程，对原始心电信号进行一定的分析处理。(ECG is the first human study and one biological signal applied to clinical medicine, it is easier to detect than other biological signals, and has a more intuitive regularity, thus ECG analysis technology for the development of medical science.However, ECG automatic diagnosis has not been widely used in clinical, ECG machine detection analysis from home and abroad, the accuracy of the automatic analysis can replace the doctor has not yet reached the level of aid can only provide...
