【摘要】 心音作为人体的一种重要声信号,在心血管疾病研究中具有重要价值。为了同时遥测心力和心率,探索心音信号通过电话通信系统传输的方式,本课题进行了心音信号4种远程传输模式的研究,传输距离为5m、10km和1000km。研究结果表明:心力和心率同时遥测可以通过电话通信系统进行远程信号传输的模式来实现。这种方法具有无创、简便、快速、费用低、可重复采用、能普及到家庭等特点。更多还原

【Abstract】 As an important human body sound signal,heart sound is of great value in the researches on diagnostics of heart diseases.This study sought to explore the methods of transmitting heart sound through the telephone correspondence system for simultaneous telemetering cardiac contractility and heart rate. Heart sounds were transmitted from a phone to another phone with 4 modes,the wirelessly transmitted distance between the two phones being 5m,10km,and 1 000 km,respectively. The results of experiments show that telemetering cardiac contractility and heart rate can be realized by the telephone correspondence system. Such methods have the advantages of being noninvasive,inexpensive,rapid and convenient; moreover,they can be used repeatedly and be available for in-home use.更多还原
