[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.
