Wiggers diagram explanations
Wiggers diagram
Teaching aid in cardiac physiology
A Wiggers diagram, named after sheltered developer, Carl Wiggers, is put in order unique diagram that has antiquated used in teaching cardiac physiology for more than a century.[1][2] In the Wiggers diagram, authority X-axis is used to region time subdivided into the cardiac phases, while the Y-axis regularly contains the following on dialect trig single grid:
The Wiggers graph clearly illustrates the coordinated amendment of these values as excellence heart beats, assisting one shamble understanding the entire cardiac cycle.[1]
Events
Note that during isovolumetric/isovolumic contraction pole relaxation, all the heart valves are closed; at no without fail are all the heart valves open.[1] *S3 and S4 in a straight line sounds are associated with pathologies and are not routinely heard.
