From: Feasibility of cardiovascular magnetic resonance derived coronary wave intensity analysis
Wave intensity analysis in the healthy coronary circulation. A pattern of 6 waves is seen in the healthy circulation. Each acts to accelerate or decelerate the flow of blood in the epicardial coronary arteries. The top panel shows the WIA pattern. Proximally originating waves are displayed above the axis and distally originating waves below the axis. The bottom panel shows the pressure (solid line) and flow velocity (dashed line)
