Physiological interactions between the two ventricles remain a challenging issue in cardiology. The aim of this study was to observe the flow patterns and energy dynamics to reveal the physiology of the right and left ventricular systems. The result shows that Energy Loss is an inevitable loss caused by the vortex flow to facilitate smooth right and left-sided Energy loss tended to correlate positively with heart rate and right ventricular stroke volume.
