Sometimes....but your heart rate also speeds up when you are nervous. And usually when people get a lie detector test they are nervous, and the test does not pick up on anxiety. That's why lie detector tests aren't used in court, they aren't very reliable (I don't care what anybody says, it's true).

yes because the sympathetic system, it works releasing adrenaline that prepares you to run away for danger, when you lie your body detects it like danger because you can get caught, this system also explain the sweating, pupil dilatation, etc. Anyway you can train yourself practicing the lie so your body "think" that is true

Yes, and if you keep on lying, your blood vessels constrict until your heart and brain explode! It's all quite violent!
