5. A study of the period of not been solved completely. In general terms it is isovolumic relaxation in normal subjects and patients possible to state that the natural frequency is proportional to the mass of the system and the stiffness of the walls, and tends to be greater when the cavity is spherical. There is no evidence that glyceryl trinitrate or propranolol caused an increase in end-systolic cavity size or a change in shape, but their effect on diastolic events might be explained by their altering the passive with heart disease;Benchimol, A.; Ellis, J.G.;Am J Cardiol,1964
