WebFeb 1, 2009 · As the balloon inflates at the onset of diastole, a sharp and deep ‘V’ is observed at the dicrotic notch (Fig. 1 ). Balloon inflation causes augmentation of diastolic pressure and a second peak is observed. This peak is referred to as diastolic augmentation. The cardiac cycle involves four major stages of activity: 1) "Isovolumic relaxation", 2) Inflow, 3) "Isovolumic contraction", 4) "Ejection". (See Wiggers diagram, which presents the stages, label-wise, in 3,4,1,2 order, left-to-right.) Moving from the left along the Wiggers diagram shows the activities within four stages during a single cardiac cycle.
