Abstract Opening the pericardium to the ambient bathing fluid surrounding the in situ perfused dogfish (Squalus acanthias) heart caused a precipitous fall in cardiac output. Cardiac output fell by 55% despite the rise of mean input pressure from subambient, to near zero levels. Lower cardiac output caused a fall in mean output pressure but not diastolic pressure as this was set by the experimenters. With the pericardium intact, the heart was filled by suction. With an open pericardium the magnitude of negative input pressures was severely reduced. None the less, for short periods within the cardiac cycle, the heart was still able to generate subambient pressures in the atrium and so draw fluid from the central veins.
