为开展心肌力学的研究,我们研制了一台左心室压力运算处理器,现应用于烧伤对心肌力学影响的电生理实验。此装置可对左心室压力信号进行微分及对数微分两种模拟运算。在示波器上显示出直接反应心肌功能的P—(dp/dt)和P—(dp/dt)/P两种向量环。通过对环体进行解析可测知心肌收缩成分缩短速度 To carry out the study of myocardial mechanics, we developed a left ventricular pressure computing processor, applied to electrophysiological experiments on the impact of burn on myocardial mechanics. This device can be left ventricular pressure signal differential and logarithmic differential two kinds of analog computing. P - (dp / dt) and P- (dp / dt) / P vector loops that directly respond to cardiac function are displayed on the oscilloscope. By analyzing the ring can be measured myocardial contractile components to shorten the speed
