Wiggers Diagram Postcard

A Wiggers diagram is a standard diagram used in cardiac physiology named after Dr. Carl J. Wiggers. The X axis is used to plot time, while the Y axis contains all of the following on a single grid: Blood pressure Aortic pressure Ventricular pressure Atrial pressure Ventricular volume Electrocardiogram Arterial flow (optional) Heart sounds (optional) By illustrating the coordinated variation of these values, it becomes easier to illustrate the relationship between these values in the cardiac cycle.
