心室纤颤微机检测系统及可靠性分析

Microcomputer system for VF detection and Reliability analysis

本文介绍了一种心室纤颤微机检测系统的双列数据缓冲区的微机接口电路设计及四种检测算法。全文着重比较了四种算法的优缺点。并针对心室纤颤信号必须十分准确、及时检测的要求,提出了多特征值并行检测法,使误判率降低为零。该系统对于设计自动除颤器和埋藏式除颤器提供了可靠的依据。

This article presents the computer interface circuit design and four detection algorithms of the double-databuffer of the microcomputer system for Ventricular Fibrillation detection. The advantage and disadvantage of the four detection are compared. Considering the requirement that the detection of Ventricular Fibrillation signal must be accurate and prompt, we propose parallel detection by multi-eigenvalues which can minimize error decision to zero, able to provide reliable basis for the design of automatic defibrillatcr and implantable defibrillator, this system has most reference value.
