Here is some of the ROTS quotes regarding dooku's stamina.
This one takes place where Dooku force pushes Obiwan temporarily out of the battle.
He gathered the Force once more in a single indrawn breath that summoned power from throughout the universe; the slightest whipcrack of that power, negligent as a flick of his wrist, sent Kenobi flying backward to crash hard against the wall, but Dooku didn't have time to enjoy it.Skywalker was all over him.
The shining blue lightsaber whirled and spat and every overhand chop crashed against Dooku's defense with the unstoppable power of a meteor strike; the Sith Lord spent lavishly of his reserve of the Force merely to meet these attacks without being cut in half, and Skywalker-Skywalker was getting stronger.
Each parry cost Dooku more power than he'd used to throw Kenobi across the room; each block aged him a decade.
He decided he'd best revise his strategy once again.
He no longer even tried to strike back. Force exhaustion began to close down his perceptions, drawing his consciousness back down to his physical form,trapping him within his own skull until he could barely even feel the contours of the room around him; he dimly sensed stairs at his back, stairs that led up to the entrance balcony. He retreated up them, using the higher ground for leverage, but Skywalker just kept on coming, tirelessly ferocious.
These quotes take place as Dooku knocks obiwan out of the battle and physical description of this part of the battle is on par with movies and in it describes dooku healing himself.
While Kenobi's bonelessly limp body was still tumbling toward the floor far below, Dooku sent a surge of energy through the Force. Kenobi's fall suddenly accelerated like a missile burning the last of its drives before impact. The Jedi Master struck the floor at a steep angle, skidded along it, and slammed into the wall so hard the hydrofoamed permacrete buckled and collapsed onto him.This Dooku found exceedingly gratifying.
Now, as for Skywalker-Which was as far as Dooku got, because by the time his attention returned to the younger Jedi, his vision was rather completely obstructed by the sole of a boot approaching his face with something resembling terminal velocity.
The impact was a blast of white fire, and there was a second impact against his back that was the balcony rail, and then the room turned upside down and he fell toward the ceiling, but not really, of course: it only felt that way because he had flipped over the rail and he was falling headfirst toward the floor, and neither his arms nor his legs were paying any attention to what he was trying to make them do. The Force seemed to be busy elsewhere, and really, the whole process was entirely mortifying.
He was barely able to summon a last surge of dark power before what would have been a disabling impact. The Force cradled him, cushioning his fall and setting him on his feet.
He dusted himself off and fixed a supercilious gaze on Skywalker, who now stood upon the balcony looking down at him-and Dooku couldn't hold the stare; he found this reversal of their original positions oddly unsettling.
There was something troublingly appropriate about it. Seeing Skywalker standing where Dooku himself had stood only moments ago ... it was as though he was trying to remember a dream he'd never actually had . . .
He pushed this aside, drawing once more upon the certain knowledge of his personal invincibility to open a channel to the Force. Power flowed into him, and the weight of his years dropped away.
He lifted his blade, and beckoned.
Skywalker leapt from the balcony. Even as the boy hurtled downward, Dooku felt a new twist in the currents of the Force between them, and he finally understood.
The bold part(where dooku heals himself) happens right before Skywalker drops down from the balcony to attack(note that there is a about second for dooku to heal himself) Dooku is 100% accurate (thus it is canon) even to Dooku's flick of the blade just prior to Anakin hitting the ground.
