Key result
A ventricle with a normal end-systolic residual volume draws blood into its cavity during diastole, and this suction effect is augmented by epinephrine.
Demonstrates the physiological presence of ventricular diastolic suction at normal arterial pressures, which is augmented by epinephrine.

Does not alter clinical practice; leaves open suction and epinephrine effects in human diastolic function.
It has been shown previously that an empty ventricle can suck in a small amount of fluid during diastole, but the question of whether a normal ventricle does so was not answered. In the present experiments it was demonstrated that even a ventricle with a more nearly normal endsystolic residual volume draws blood into its cavity and that this ventricular vis a fronte is augmented by the action of epinephrine.

Brecher et al. (1958) studied Normal ventricular function. Epinephrine vs. Baseline was evaluated on Ventricular diastolic suction. A ventricle with a normal end-systolic residual volume draws blood into its cavity during diastole, and this suction effect is augmented by epinephrine.
