对心音进行听诊是心脑血管疾病和呼吸系统疾病主要诊断手段之一,本文详叙了通过利用MSP430单片机进行数据处理和参数显示,并用MATLAB中小波分析和神经网络程序对信号进行数字处理和分析,达到实时显示心音信号波形和心率的实验板设计过程,对改变用听诊器及自己的经验对心音做出主观分析和判断,难以准确捕捉人体内脏发出的微弱却非常重要的生理声音的传统方法,具有一定的实用价值。
Auscultation of the heart sound is one of the main diagnostic tools for cardiovascular diseases and respiratory diseases. This paper describes in detail the data processing and parameter display by using the MSP430 microcontroller and digital processing and analysis of the signals by MATLAB wavelet analysis and neural network programs , To achieve real-time display of heart wave signal waveform and heart rate of the experimental board design process, change the use of stethoscope and their own experience to make subjective analysis of heart sounds and judgments, it is difficult to accurately capture the human body visceral weak but very important traditional physiological sound method, Has a certain practical value.
