The first phase is a brief isovolumetric contraction, lasting about 0.05 s and a longer ejection phase of about 0.30 s. The isovolumetric contraction causes left ventricular pressure to rise above atrial pressure, which closes the mitral valve and produces the first heart sound.
Ejection fraction goes down and. ventricular volume increases. As a result of increased volume. the thickened part of the inter-ventricular septum is pushed. away from the outlet area. Left ventricular outflow tract. obstruction and gradient decreases and dynamics of flow. returns to normal.
