[The curve of the intraventricular pressure-volume relationships is not mono-exponential].

The graphic and statistic investigations have let us to assert that the right ventricular P/V relationship's curve is characterized by two successive segments: linear and exponential respectively. We have proposed an interpretation based on Roach's and Burton's works. Interest of information about this curve is double: 1) it is a function of the ventricular cavity volume; 2) it gives a general idea about the mode of ventricular filling.

[Pressure-volume relationship in the right ventricle].

The curve of the pressure-volume relationships of the right ventricular cavity is not a mono-exponential one. It can be characterized by the presence of two successive segments: linear and exponential. The points that constitute the first of them could not be subjected to Starling's law. This is material for the physiopathology of the tamponade.

[Tension-volume relationship of the wall of the isolated right ventricle].

The variations of tension on the wall of the isolated right verticle have been observed on 18 dogs. The Tension/Volume curve we got can be superimposed to that obtained by pressures. The wall of the right ventricle itself (the radius of the curve in the cavity and the wall-thickness) seems to vary only with the changes in its tension in a rather small part of the curve.
