Temporal and Spatial Heterogeneity of Blood Supply to the Heart: Visualization and Interpretation

Blood flow of the heart muscle (the coronary circulation) exhibits both temporal and spatial heterogeneity. In this paper, the unique blood velocity waveform during a cardiac cycle, the flow fluctuation of a longer period and the within-layer spatial flow heterogeneity of the coronary circulation are described with a reference to the pathogenesis of angina pectoris and myocardial infarction.
