Figure 1. Circumflex coronary pressure (P), flow (Q) and wave intensity from an adult sheep.

Figure 1

The major waves, which are also present in humans, are labelled according to wave type (FCW, FDW, BCW, BDW; forward/backward compression/decompression wave) and phase of the cardiac cycle (ic, isovolumic contraction; sys, early‐systole; dia, early‐diastole). Decompression (i.e. pressure‐decreasing) waves are shaded.
