LabVIEW在心音信号研究中的应用

心音信号是人体重要的生理信号之一,它可以直接反应人体的生理病理信息。在本文中利用LabVIEW对心音信号进行采集、去噪,并利用功率谱估计对心音信号进行分析处理,可以明显的区分出正常与异常的心音信号,为正确诊断心血管疾病提供一定的帮助。

Heart sound signal is one of the most important human physiological signal, it can be the direct reaction of physiological and patho-logical information of the human body.ln this paper, nsing LabVIEW is collected, the heart sounds signal denoising, and using tile power spec-tral estimation of heart sound signal analysis and processing, can be a clear distinction between normal and abnormal heart sound signal, pro-vides certain help for the correct diagnosis of cardiovascular diseases.
