本文介绍了一种用单板机控制的心功能监测仪,能对导纳心动图进行实时、自动地处理及计算,提出了一种逐点基线校正算法以实时,逐拍地消除呼暖干扰一些用来可靠地识别dy/dt波的X点及心电图R波的算法。临床实践证明,得到的结果和手工测量、计算的结果一致。 In this paper, we introduce a cardiac function monitor controlled by a single-chip microcomputer, which can process and calculate the admittance cardiogram in real time and automatically, and propose a point-by-point baseline correction algorithm to eliminate the warm disturbance Some algorithms to reliably identify the X-point of the dy / dt wave and the R-wave of the electrocardiogram. Clinical practice has proved that the results obtained and manual measurement, the calculated results.
