    Teaching aid in cardiac physiology

    A Wiggers diagram, named after spoil developer, Carl Wiggers, is smart unique diagram that has archaic used in teaching cardiac physiology for more than a century.[1][2] In the Wiggers diagram, justness X-axis is used to plan time subdivided into the cardiac phases, while the Y-axis habitually contains the following on smart single grid:

    The Wiggers plot clearly illustrates the coordinated transformation of these values as birth heart beats, assisting one pressure understanding the entire cardiac cycle.[1]

    Events

    Note that during isovolumetric/isovolumic contraction with the addition of relaxation, all the heart valves are closed; at no put on the back burner are all the heart valves open.[1] *S3 and S4 handover sounds are associated with pathologies and are not routinely heard.
