Summary

[edit]
Description
Català: Diagrama de Wiggers, mostra els esdeveniments del cicle cardíac en el ventricle esquerre.

En el gràfic de la pressió auricular:

"a" correspon a la contracció auricular
"c" correspon a l'increment de pressió degut a la força exercida per la vàlvula mitral després de tancar-se
"v" correspon a l'ompliment auricular passiu.

A l'electrocardiograma:

"P" correspon a la despolarització auricular
"QRS" correspon a la despolarització ventricular
"T" correspon a la repolarització ventricular

En el fonocardiograma:

1r: So S1, és el so causat per la reberberació sanguínia al tancar-se la vàlvula mitral.
2n: So S2, és el socausat per la reberberació sanguínia al tancar-se la vàlvula aòrtica.
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.
