   Abstract:
   A description is given of the development of a general microcomputer-based system to perform biological signal processing concerning clinical and experimental protocols in cardiology. In intensive care units the software of this system enabled the clinical staff to acquire several signals simultaneously (such as cardiac chamber pressures, arterial pressure, respiratory flow, ECG, and EEG) and to interface an IBM PC compatible with other devices (for example a thoracic electrical bioimpedance system) which can furnish important ventricular stroke volume measurements. On the other hand, in experimental protocols, where the relationship between the latter signals with action potentials from peripheral nerves was investigated, it was necessary to design a window discriminator (WD) that allowed the study of point processes related to the neural control of the cardiovascular system. This WD was connected to the microcomputer through a parallel interface with minor modifications. The software was divided into modules. To evaluate the signals after acquisition several basic routines are available (smoothing, statistical and spectral procedures)
