心脏收缩时间间期(STI)的测定是一种无创性的左心室功能的检查方法。目前测定STI的传统方法是在多道生理记录仪上测量心音图、心电图和颈动脉搏图,然后加以分析计算,但其代价高,精度差,费时费力。此微机心功能检测仪,用一个专用插件置于微机内,联接相应的传感器,并配有研制的专用软件,在测试心功能方面取代了多道生理信号记录仪,可准确、迅速地给出测量结果。
The systolic time interval (STI) is a noninvasive method of checking left ventricular function. At present, the traditional method for measuring STI is to measure the phonocardiogram, electrocardiogram and carotid artery pulse graph on a multi-channel physiology recorder and then analyze and calculate them, which is expensive, time-consuming and laborious. This microcomputer heart function detector, with a dedicated plug-in placed in the computer, coupled with the appropriate sensors, and with the development of special software, in the test of cardiac function to replace the multi-channel physiological signal recorder can be accurately and quickly given Measurement results.
