A multichannel data acquisition package for reduction of systemic and coronary hemodynamic data that utilizes a personal microcomputer is described. The system provides a printout of heart rate, maximal rate of left ventricular pressure development (+dP/dt), maximal rate of ventricular relaxation (-dP/dt), absolute and normalized myocardial segment lengths, the degree of shortening of the segment over the cardiac cycle, systolic, diastolic, and mean coronary blood flow velocities, left ventricular systolic and end diastolic pressures, and systolic, diastolic, and mean aortic blood pressure from six channels of input data. Obtained values are precisely linked to the cardiac cycle. To illustrate the output of this system, data obtained by reading strip-chart records are compared to microcomputer-derived values in conscious, instrumented dogs.
本文描述了一种利用个人微型计算机来处理全身和冠状动脉血流动力学数据的多通道数据采集程序包。该系统可打印出心率、左心室压力上升最大速率(+dP/dt)、心室舒张最大速率(-dP/dt)、绝对和归一化心肌节段长度、心动周期中节段缩短程度、收缩期、舒张期和平均冠状动脉血流速度、左心室收缩压和舒张末期压力,以及来自六个输入数据通道的收缩期、舒张期和平均主动脉血压。所获得的值与心动周期精确关联。为说明该系统的输出结果,将通过读取带状图表记录获得的数据与在清醒、植入仪器的犬只中由微型计算机得出的值进行了比较。
