[Quantitative evaluation of coronarographic findings using a point scoring system].

For the quantification of pathologic changes of the coronary arteries a score system is shown which consists for each stenosis of two factors. One for the degree of the stenosis and one for the localisation. The latter is adjusted according to the perfusion type (right dominant), balanced, left dominant coronary perfusion). The left ventricular score also consists of two factors. One for the quality of dysfunction (hypokinesia, akinesia, paradoxical pulsation) and one for the localisation (seven segments of left ventricular wall).

E1A calculating unit for the determination of the peak measured contraction velocity of the contractile elements.

An analog calculating unit is described, which is able to differentiate the left ventricular pressure and divide dP/dt by P, where P is the absolute pressure value. The parameter dP/dt/P is called the peak measured velocity (Vpm) with the dimension s(-1). The unit has an appropriate accuracy for division, three ranges and easy to handle calibration steps. The time constants for the various ranges are 40, 8 and 4 ms.
