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.
