Luke Skywalker - It's impossible I'm afraid. It would break all the laws of natural science.
The reason is that heart rate (or pulse as you call it) multiplied by pulse pressure (the difference between systolic and diastolic pressures) is proportional to cardiac output. This is expressible in the form of an equation : - {HR x C.PP = CO} where C is compliance of the wall of the root of the aorta.
So at any instant HR x PP is a constant (since C is already a constant by definition).
If you vary HR (or as you say "increase your pulse"), then the left hand side of the equation will not equal the right hand side, -unless PP decreases correspondingly to compensate for the higher HR. i.e., if you increase your pulse rate your pulse pressure automatically and inevitably must be decreased.
This isn't to say cardiac output doesn't vary. Of course it does, all the time. But at any instant the equation holds and you can't alter HR, PP or CO in isolation from the other two parameters.
