ABSTRACT
This chapter describes a man who died after a gunshot wound that entered the right atrium and exited from the right ventricle without entering the cardiac septa or the left side of the heart. Whether the human cardiac ventricles can create a negative pressure or have a suction-like action has been debated for years. Bloom concluded that the ventricle was able to fill only because it had developed a negative pressure. Bloom concluded that the ventricle was able to fill only because it had developed a negative pressure. Fowler and associates confirmed the observation of Brecher that obstruction to left ventricular inflow did indeed result in negative left ventricular diastolic pressures; obstruction to right ventricular inflow caused negative right ventricular diastolic pressures. Rapid exsanguination was produced by inserting a rubber tube into the right ventricular cavity, the same site of bleeding as in a patient.
