Sažetak

Opis
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 image was updated to extend the range of colors and to correct an error in the original - aortic pressure now correctly exceeds left ventricular pressure in the end-systolic period (e.g. see Sugawara M, Uchida K, Kondoh Y, et al. Aortic blood momentum--the more the better for the ejecting heart in vivo? Cardiovasc Res 1997; 33(2): 433--46). .
