Summary

DescriptionWiggers Diagram.svg	English: A Wiggers diagram, showing the cardiac cycle events occuring in the left ventricle. In the atrial pressure plot: wave "a" corresponds to atrial contraction, wave "c" corresponds to an increase in pressure from the mitral valve bulging into the atrium after closure, and wave "v" corresponds to passive atrial filling. In the electrocardiogram: wave "P" corresponds to atrial depolarization, waves "QRS" correspond to ventricular depolarization, and wave "T" corresponds to ventricular repolarization. In the phonocardiogram: The sound labeled 1st contributes to the S1 heart sound and is the reverberation of blood from the sudden closure of the mitral valve (left A-V valve) and the sound labeled "2nd" contributes to the S2 heart sound and is the reverberation of blood from the sudden closure of the aortic valve.

This a revision on the work by DestinyQx whose original image can be found here: http://commons.wikimedia.org/wiki/File:Cardiac_Cycle_Left_Ventricle.PNG

The original image incorrectly portrays aortic valve closure which occurs when left ventricular pressure falls below aortic pressure. This has been corrected in this png revision. Some spelling has also been corrected. The credit for the original drawing goes to DestinyQx.
