Pulse Rate

Is there any connection between human pulse rate and blood pressure ?

Is there any connection between human pulse rate and blood pressure. What is normal average pluse of a human being. If it is high the blood pressure too goes up and visa versa?

Yes there is, and it's a very precise mathematical relationship, expressible in algebraic form, but in order to understand it, first you must distinguish between what you are calling "blood pressure" (which doesn't really exist) and its two component parts, (which do). These are 'pulse pressure' and 'diastolic' pressure. They are real, and do exist. "Blood pressure" doesn't. It only lies in the collective imagination of the medical profession.

The three determinants of PP, the pulse pressure, are (a) heart rate, (b) cardiac output, and (c) wall compliance of the root of the aorta**, so pulse rate HR affects it greatly. Much more so than cardiac output does.
So there IS a connection there, between human pulse rate and pulse pressure.

But human heart rate does NOT affect the diastolic pressure Pd at all, because that is simply the mathematical product of the amount of blood flowing along the arteries at any time, times the resistance to flow presented by those arteries.

Pulse pressure, when added to diastolic pressure, gives the value of systolic pressure. The equation connecting pulse pressure, heart rate, cardiac output, and C, the compliance, is in the Source I quote below. If you find any difficulty understanding it please feel free to email me and I'll be glad to help.

Miguel's posting is simply wrong. BP often goes down as heart rate rises, as Techwing correctly states.

But Techwing's posting is also wrong for the same reason, because (a) a faster heart rate very frequently correlates not only to higher pressures but also to lower ones and (b) the algebraic relationship between CO, HR, CO, and C described above is in no way 'loose'. It's so precise that it is possible to calculate heart rate to an accuracy of better than +/- 1 bpm, and pressure to within +/- 1 mm.Hg, and cardiac output to within 1mil/minute, simply from BP readings.

NOTE ** There is a fourth determinant, which is fairly obscure, and goes unrecognized, and it is the resonance of the aorta, which amplifies the pulse pressure wave as it traverses the large arteries, making it appear to be greater than it is, when measured. But I don't think that need concern you, unless you want to follow it up. You can read about it in an essay called "The Resonant Aorta"
