Each individual exposure in an angiocardiogram gives a picture of the arrested motion of the heart in successive stages of opacification. By combining these isolated views in a graph, a continuous dynamic process can be visualized. The chambers of the heart can be analyzed separately, and by correlating the opacification in the various chambers, the function of the heart as a whole can be studied.
