Does a lower pulse rate ammount to higher blood pressure? Does BP cause tinnitus?
The rate at which your heart beats is related to the blood pressures in two ways, but to understand this, first you must accept that there’s no such thing as “blood pressure”. There IS ‘diastolic pressure’, which actually drives blood round, and then there IS ‘pulse-pressure’ which doesn’t. It’s no more than a shock wave, and adding the two together gives you ‘systolic pressure’. Diastolic pressure is unrelated (mathematically) to pulse rate. Pulse pressure however, as you rightly say, very much depends on pulse rate, -but in two different and opposing ways. First, it increases (naturally) with stress and activity, rising linearly with cardiac output, and so when the heart is pumping out more (total) blood per minute, both pulse RATE and pulse PRESSURE increase together, because the brain causes the heart not only to pump faster, but also to pump out more blood per beat. Pulse pressure is proportional to the amount of blood pumped out per beat and therefore increases with cardiac outpu
