any relation between blood pressure and pulse rate in human?

Question

is th pulse rate higher in those whose blood pressure are high ? if so is there any rate ?

Answer 1

Blood pressure is the pressure exerted by the blood at right angles to the walls of the blood vessels. Unless indicated otherwise, blood pressure refers to systemic arterial blood pressure, i.e., the pressure in the large arteries delivering blood to body parts other than the lungs, such as the brachial artery (in the arm). The pressure of the blood in other vessels is lower than the arterial pressure. Blood pressure values are universally stated in millimetres of mercury (mmHg).

In medicine, a person's pulse is the throbbing of their arteries as an effect of the heart beat. It can be felt at the neck, at the wrist and other places.
Pressure waves move through the blood vessels, which are pliable; it is not caused by the forward movement of the blood. When the heart contracts, blood is ejected into the aorta and the aorta stretches. At this point the wave of distention (pulse wave) is most pronounced, but relatively slow-moving (3 to 5 m/s). As it travels towards the peripheral blood vessels, it gradually diminishes and becomes faster. In the large arterial branches, its velocity is 7 to 10 m/s; in the small arteries, it is 15 to 35 m/s. The pressure pulse is transmitted 15 or more times more rapidly than the blood flow.
The term pulse is also used, although incorrectly, to denote the frequency of the heart beat, usually measured in beats per minute. In most people, the pulse is an accurate measure of heart rate.

Answer 2

Let me make this simple.............

All of the body's systems including the cadiovasular system has a compensatory function to maintain metabolic stability.

What does that mean in relation to your question?

Well, you asked about the relationship between the pulse and blood pressure. Arteries perfuse organs...in other words they deliver oxygen and nutrient carrying blood.

If the blood pressure drops.....less blood is delivered....and the body compensates by raising the pulse. So that the same amount of blood is delivered as compared to before the blood pressure drop.

Of couse it is a little more complicated than this is real life....but for the sake of answering a Yahoo question....this is all you need to know.

Hope this helps!

Answer 3

Usually when blood pressure goes up, the pulse rate also increases. This is because when one gets excited or stressed out the pulse rate increases together with the blood pressure.

Answer 4

Yes, as your pulse rate goes up so does you're blood pressure. You're heart is pumping faster, meaning more blood being pumped through your arteries at a quicker rate. Regular heart rate is between 60-100bpm, average being some between 68-75. Though it usually depends on the person.

Answer 5

Sometimes it is, other times it isn't. It is a complicated question. Are you speaking of otherwise healthy people with idiopathic hypertension(HTN)? Are you speaking of short term acute hypertension of known etiology? In either case- have the people been given meds (like beta blockers) that reduce both heart rate (HR) and BP? What is the etiology of the HTN? What is the demographic (pediatric, geriatric etc...)? All of these factors will determine the answer to your question.

Lets assume otherwise "healthy" middle aged people who suffer mild to moderate HTN. Because HTN in this demographic is closely related to obesity and a sedentary lifestyle then one could assume that they also have statistically higher heart rates then those of normal BP. We can assume this because exercise increases stroke volume (SV) and decreases HR. We cannot say that the HTN "caused" the higher heart rate, only that there is an association between them (a common factor).

In some extreme cases there are well known relationships between HR and BP- Cushings Triad comes to mind, but this is an extreme example.

Jordon S answer was somewhat misleading. In cases of hypovolemic shock the cardiac output (CO) is maintained by an increased HR in the face of decreasing SV, but the blood pressure varies little (especially in children) until the degree of systemic compromise is very severe. Again there is NO SINGLE ANSWER to your question. It all depends on the specifics.

Answer 6

No pulse rate may or may not be high in those with high BP,.. The problem with forum like Yahoo questions is people like u will ask one quesn and will be expecting some answer, without seeing the patient a truly specialised person will not answer, because it may be different for each

Answer 7

Obesity is associated with high insulin and leptin levels. Studies also suggest that high levels of insulin and leptin increase sympathetic nervous system (SNS) activity and engender increased chronotropy, vasoconstriction and antinatriuresis that may contribute to the pathogenesis of obesity related hypertension. Sympathetic modulation of cardiovascular responses requires good baroreceptor sensitivity and optimal vascular compliance. The vascular changes associated with isolated systolic hypertension (ISH) have been shown to modify baroreceptor sensitivity and vascular compliance and may mitigate sympathetic modulation of cardiovascular responses and attenuate the hypertensive effect of obesity. The purpose of this study is to examine the differences in the relationship between body mass index, pulse rate (PR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) among participants with normal blood pressure and ISH using data from the third National Health and Nutrition Examination Survey. Data from 13,761 non-institutionalized adults 18 years and older not receiving antihypertensive therapy were analyzed. Results showed that PR, SBP and DBP increase with increasing BMI. The rise in PR, SBP and DBP with BMI is higher among participants with normal blood pressure than among those with ISH. We concluded that increasing level of obesity is associated with a rise in pulse rate and blood pressure but the effect of obesity on blood pressure and pulse rate might be weaker among participants with ISH.

On the border between orthostatic normal regulation and hypotension, the size of the blood pressure amplitude in upright position is dependent upon the pulse frequency and the pulse respiration quotient. The relationship between the blood pressure amplitude and the pulse frequency is linear and lends itself to the setting up of an orthostasis quotient. As into this quotient enter only data of upright position, we speak of a "standing reaction", the result of which satisfactorily corresponds with certain criteria of the "standing-up reaction" noticed by us so far. The orthostasis quotient coincides better with the clinical picture than the results of the standing-up reaction and separates the orthostatically stable person more precisely than the orthostasis index.
