Event
lines a-k added.
- a : Commencement of atrial
contraction, affecting the ventricular septum and the posterior wall
- b : Point of maximum effect of
atrial contraction on the left ventricle (LV)
- c : Closing of the mitral valve
- d : Onset of movement of VS,
towards its position in systole
- e : Onset of movement of the
posterior wall, towards its systolic position
- f : First systolic maximum of VS,
in the direction of LV
- g : Onset of the renewed systolic
movement of VS in the direction of LV, which is simultaneous with the closing of
the aortic valve
- h : Point of maximal thickness of
the posterior ventricular wall
- i :Second systolic maximum of VS,
in the direction of LV
- j : End of the fast relaxation
(thickness reduction) phase of the lateral posterior wall of LV
- k : End of the fast relaxation
(thickness reduction) phase of VS
