y doz increasing total pripheral resistance increse your diastolic pressure. effects on systolic/pulse presure

Systolic is the top number in your blood pressure.  It represents the pressure against arterial walls when the heart is contracted.  The diastolic pressure represents the pressure against the arterial walls when the heart is relaxed, or at the beginning of a cardiac cycle.  What affects vasoconstriction or vasodilation are neurotransmitters.  These occur naturally in your body, but have been replicated for medical use.  Vasodilation is when your vascular system, or your veins, open up.  (A good example of this is Nitro Glycerine.) With more space, there is less pressure.  Vasoconstriction is when the vascular system constricts, (A good example of a vasoconstrictor is dopamine.) so less space, more pressure. With lower pressure, the heart thinks it has to work harder to fill the "container", (container being your vascular system.) so it increases its rate to compensate.  Higher pressure means the heart is having to work harder to get the liquid (blood) where it needs to go.  Picture a pump system.  You need a pump, (your heart) a container (vascular system) and liquid volume. (Blood.)  THe point would be to keep the container filled, volume circulating, and the pump working.  \n     Hope that clears it up for you a bit!

Have your blood pressure checked.

Usually it is the inverse relationship.  When people's BP drops their HR has to increase to compensate for the decrease in blood flow.

This is not actually so.  To quote from another source:\n\n"In the past, most attention was paid to diastolic pressure; but nowadays it is recognised that both high systolic pressure and high pulse pressure (the numerical difference between systolic and diastolic pressures) are also risk factors."\n\nOr, to put it a more obvious way, if only one number was really important, why would anyone bother writing down two?  The systolic number tells you about how hard the heart works at maximum, and the diastolic can tell you about the minimum flow and the quality of your veins.  Those are both rather obviously good things to know!

A lot of people think that it is the systolic that you should be worried about, but it really should be the diastolic.  Anyone with diastolic over 100 can start to have symptoms and it's the high diastolic that can indicate a potentially serious problem (for example, stroke).

If your blood pressure is over 140/90, then you have high blood pressure or hypertension ... provided that the BP measurement was taken correctly, and you were well rested when the measurements were taken.  Hypertension if uncorrected, damages your heart, kidneys, and increases the risk of stroke.  All these occurs while you're feeling ok ... that's why it's often coined as the "silent killer".\n\nYou are pre-hypertensive.  Not normal.  This subgroup is there to emphasize the importance of prevention.  That means more exercise, watch the salt in your diet, quitting or cutting down on alcohol, smoking, etc.  Lifestyle changes mostly.  The good news is that you don't need to take any medications.\n\nHope that helps.

you'll get the same results.....the whole point is to get your heart rate elevated for a long time...doesn't matter if you swim/run/jump/workout....=]

The systolic of 148 is high. You want to look into more exercise, cutting back on salt and similer things. Your diastolic is good. The big difference between them seems strange to me but I'm not a Doc. I'd ask one about that big a difference. My Diastolic is typicaly around yours  but my systolic is normally 100-120.

Altered hemodynamic response to isosorbide dinitrate in essential hypertension\nBM Pannier, T Kando, AA Safarian, RN Isnard, BE Diebold, and ME Safar\n\nRelaxation produced by nitrates on venous, arteriolar, and large arterial vessels is well known but has never been studied in human hypertensive aortas studied in vivo. In this investigation, the effects of acute oral administration of 20 mg of isosorbide dinitrate were evaluated in 12 patients with sustained essential hypertension and nine normotensives of the same age. Noninvasive measurements of systolic, diastolic, and mean arterial pressure, carotid-femoral pulse wave velocity and aortic-arch diastolic diameter using suprasternal echocardiography were determined before and 3 hours after drug administration. In normal subjects, isosorbid dinitrate significantly decreased systolic blood pressure and pulse pressure but did not affect diastolic and mean arterial pressure. In contrast, in hypertensives, the same dosage of isosorbid dinitrate decreased together systolic, diastolic mean, and pulse pressure. In both populations, pulse wave velocity decreased significantly whereas aortic arch diastolic diameter increased markedly. The increase was observed mainly in normal subjects. The study provided evidence that (1) both in normal subjects and hypertensives, isosorbide dinitrate caused an increase in aortic diameter together with an increase in arterial distensibility; and (2) the changes in mean arterial pressure were significant only in hypertensives, indicating that the altered vasodilator response in essential hypertension is not endothelium-mediated

Blood pressure = Cardiac output * total peripheral resistance.\n\ncardiac output is the amount of blood pumped out by the left ventrical per minute~5L/min\n\nCardiac output= heart rate * stroke volume\n\nheart rate is number of times the heart beats per minute and stroke volume is End systolic volume - end diastolic volume. \n\nWhen your start to run, there will be a mass sympathetic discharge from your brain. So your hearts pumps harder and faster. Heart rate increases and heart contractility increases. so cardiac output increases from 5 L to say 8L or more. However BP does not increase as much because total peripheral resistance acturally decreases instead of incrases. As you run, the mucles that are oxygen starved release vasodilators into the blood vessels. These cause the smooth muscle around the arterioles to vasodilate. Therefore resistance to blood flow actually decreases. Hope this explains what you've been looking for.

There are many factors in deciding how a regular TM will be done. ( there are also drug induced TM) The first is your age. There's a formula for this. It is:220-age x 85=. This result is called '85%'of your target heart rate,and determines what your heart rate should increase to in order to get a good test. Now sometimes this isn't possible. Again, there are several factors involved. You may not be in very good shape, physically. You may be on medications that don't allow your H.R. to increase. You may have respiratory limitations. If you can up your H.R. to 70%, this should end as a good test, too. Just ask your doctor. It's his call.\n\nThe reason you want to raise your H.R. is so they can see what your heart does under stress.Thus, a STRESS test. I'll tell you now, how they prepare you for this test. The first thing they will do is put sticky type patches on your chest. Then they will connect electrodes to the patches.(No! there is no electric current involved). This allows a visual view of different areas of the heart. At this point, they will start your walk. It will be very slow for the first 3 minutes, and then they will tell you seconds before they increase the grade and speed of the T.M. So, every three minutes you will experience this gradual increase in speed and grade. Remember, their trying to get  your H.R. to rise. They will talk to you all along to insure you are doing alright. Don't be frightened. You will be watched carefully. You must communicate though, and don't try to be the tough guy/girl.Don't be a wimp either. No. This not an easy test. You will be tired and winded when you're finished. Just do your best. This is a very good test.They will be able to determine what they need to in order to better see what's going on. When completed, they will seat you and watch your recovery for about ten minutes. This a part of the test. They want to see how quickly your heartrate returns to normal. This is called you're resting heartrate. Again, talk to them. Ask your questions, and get answers that make sense to you. Many people do not do this. They get home and start questioning their understanding.\n\nI also want to leave you with some advise. I am a Psy. Therapist, specializing in cardiology. This is what I tell all of my patients. First; do not be intimidated by doctors or health care workers in general. You deserve to get every bit of information necessary  to  satisfy all of your medical concerns. If there is something you don't understand, do not settle. Often you will need to be assertive because  when you do understand, you'll be better equiped to take care of yourself in the future. It's very important to have a partnership with your doctor, not a dictatorship. There are so may great docs out there, but if you're the slightest bit uncomfortable with your relationship, find another doctor. It is really  as simple as that. You will find the one that fits you.\n\nGOOD LUCK.\n\ngrizz\n\nP.S.  E-mail me, if you would like. I would be very happy to speak with you.\n\nDuckling702@yahoo.com

Diastolic pressure is the pressure in the circulatory system in between heartbeats. The blood isn't at any pressure inbetween beats, whether you've just exercised or are sleeping.  If anything, I would guess it might be a little lower if blood vessels dilate (expand) to let off some heat after exercise, as the volume of space for the same amount of blood might increase a little?

The increased heart rate will maintain the cardiac output, not the BP.  \n\nThe blood pressure will be maintained by increased sympathetic tone, leading to vasoconstriction.  Sympathetic tone is increased by endogenous catecholamines (adrenalin/epinephrine)

It depends on the duration of the "high" pulse. I would be concerned if you for example had a pulse rate of 130 or above for several hours.\n\nOn the other hand 130 pulse rate during strenuous exercise for short periods of time would not be a cause for concern unless there were other symptoms involved such as an irregular heartbeat.\n\nYour Doctor is your best source of information.
