FIGURE 3.

Vagal tank and the 3 Rs of cardiac vagal control: effect of a depleting factor. Illustration of the vagal tank and the three Rs (resting, reactivity, and recovery) with a factor depleting cardiac vagal control. In regards to the post-event: A – displays a situation where the level of carrdiac vagal control during the post-event is higher than the initial level at baseline, B – displays a situation where the level of cardiac vagal control at post-event is similar to the initial level at baseline, and C – displays a situation where the level of cardiac vagal control at post-event did not recover to the point of its initial baseline level.
