Electronic circuit detects left ventricular ejection events in cardiovascular system [PDF]
, 1972 Electronic circuit processes arterial blood pressure waveform to produce discrete signals that coincide with beginning and end of left ventricular ejection. Output signals provide timing signals for computers that monitor cardiovascular systems.

Ventricular Diastolic Suction at Normal Arterial Pressures [PDF]
Circulation Research, 1958 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 ...
