| 摘要 |
<p>The invention concerns a system for representing and analysing pressure variables comprising pressure sensors [blood pressure, intracardiac pressure], means for processing signals delivered by said sensors and means for displaying variations of said signals, the processing means including a plurality of inputs for receiving analog signals from different sensors. The invention is characterised in that each input is connected to a sampling circuit supplying a digital signal used by a calculator to carry out processing operations including: re-sampling of the displayed or recorded signals, analysing the frequency of said sampled signal relative to a range of target frequencies recorded in a storage unit, displaying and recording temporal variations of the signals corresponding to slow waves, determining the lag between the slow waves of the signals corresponding to two distinct inputs.</p> |
