Metal Gear Strategy Help With Torture Scene On Metal Gear Solid For Ps1?

Help with torture scene on Metal Gear Solid for ps1? - metal gear strategy

A friend and I can not on the scene after the fight against torture Sniper Wolf (I think it's the name). Bad electrocute him, and that is to hit the circle quickly in order to survive, but it kills. We tried to see strategy guides, but they all say the same thing. Has anyone played this game and managed to overcome this part? If so, can we help you? Thanks
