Summary

[edit]
Description
Português: diagrama de Wiggers, mostrando os eventos do ciclo cardíaco ocorrendo no ventrículo esquerdo.

No gráfico de pressão atrial: a onda "a" corresponde à contração atrial, a onda "c" corresponde a um aumento na pressão devido ao abaulamento da válvula mitral para dentro do átrio após o fechamento, e a onda "v" corresponde ao enchimento atrial passivo.

No eletrocardiograma: a onda "P" corresponde à despolarização atrial, as ondas "QRS" correspondem à despolarização ventricular, e a onda "T" corresponde à repolarização ventricular.

No fonocardiograma: O som rotulado como "1º" contribui para o som cardíaco S1 e é a reverberação do sangue do fechamento súbito da válvula mitral (válvula AV esquerda), e o som rotulado como "2º" contribui para o som cardíaco S2 e é a reverberação do sangue do fechamento súbito da válvula aórtica.
