FIGURE 4.

Vagal tank and the 3 Rs of cardiac vagal control: effect of a replenishing factor. Illustration of the vagal tank and the three Rs (resting, reactivity, and recovery) with a factor replenishing cardiac vagal control. In regards to the post-event: A – displays a situation where the level of cardiac vagal control during the post-event is higher than the level during the baseline, B – displays a situation where the level of cardiac vagal control at post-event is similar to the event level, and C – displays a situation where the level of cardiac vagal control at post-event returned to baseline level.
