A differentiable, periodic function for pulsatile cardiac output based on heart rate and stroke volume.

Many mathematical models of human hemodynamics, particularly those which describe pressure and flow pulses throughout the circulatory system, require as specified input a modeling function which describes cardiac output in terms of volume per unit time. To be realistic, this cardiac output function should capture, to the greatest extent possible, all relevant features observed in measured physi...

Regulation of cardiac output through stroke volume.

Heart rate and stroke volume contribution to cardiac output in swimming yellowfin tuna: response to exercise and temperature.

Cardiac performance in the yellowfin tuna (Thunnus albacares, 673-2470 g, 33-53 cm fork length, FL) was examined in unanesthetized fish swimming in a large water tunnel. Yellowfin tuna were fitted with either electrocardiogram electrodes or a transcutaneous Doppler blood-flow probe over the ventral aorta and exposed to changes in swimming velocity (range 0.8-2.9 FLs-1) or to an acute change in ...

Heart stroke volume and cardiac output by four-dimensional ultrasound in normal fetuses.

OBJECTIVE To establish reference intervals for fetal heart stroke volume and cardiac output with gestation. METHODS Fetal heart ventricular volumes were measured using the four-dimensional (4D) spatiotemporal imaging correlation (STIC) ultrasound technique in 140 normal singleton pregnancies at 12-34 weeks' gestation. The Virtual Organ Computer-aided AnaLysis (VOCAL) technique was used to obt...
