Stroke volume and blood pressure

Common Questions and Answers about Stroke volume and blood pressure


Avatar m tn I am 18, and my systolic blood pressure is 155 and diastolic 55 and my heart beat is 59, so am I sick or something, I have little dizzynes sometimes and my vision blanks when I stand up...
Avatar n tn 123/109 is moderate hypertension (Stage 2). The difference between the systolic and the diastolic is the pulse pressure. You have a low or narrow pulse pressure of 14 mmHg. 123 - 109 = 14mmHg. Excerpt from "Pulse Pressure....The Other Blood Pressure!" by Eva Martinez... "It is very rare to get a pulse pressure reading of less than 40 mmHg. Chances are, if you receive one that is significantly lower, than you’ve just done the calculations incorrectly.
Avatar f tn the heart, and constrict blood vessels, to prevent pooling of blood in your veins, which eventually will increase the stroke volume, but this is noticed as palpitations. A systolic blood pressure of 87 is too low. PVCs may reduce the blood pressure, but this is just speculations from me. If something should be investigated by your doctor it's the blood pressure, not the heart rate, though I suspect they are somehow linked, see above.
5856747 tn?1403352282 What are the symptoms of raised blood pressure? Most people with a moderately raised blood pressure are unaware of it and it is only discovered on routine examination. Severely raised blood pressure may give rise to headaches and a thumping sensation in the chest and vague feelings that all is not well. How is hypertension diagnosed? : There are two blood pressures. One is when the heart contracts and this is called systolic blood pressure.
1591333 tn?1297737019 For instance heart failure increases blood volume and the kidneys react as if the individual is losing blood...the increase of volume further distresses the heart and kidneys continue to believe the system is losing blood. Also, the heart rate and dilation of the heart will continue to rise with a low cardiac output.
Avatar f tn monitoring blood pressure is a difficult thing when you are constantly on the move, thinking different things, having different emotions and even eating. Everything we do affects blood pressure and we can only work on averages. If blood pressure didn't keep changing, we couldn't function very well. The only way to get a fairly accurate blood pressure reading from your body is to relax for 30 mins and empty your mind of all emotional thoughts. This is not possible for the majority of people.
Avatar n tn These risk factors are tied to hormonal fluctuations, changes in blood volume, tendency to form blood clots, and other physical changes that affect a woman in different stages of life." Go through this link for some more info You need to be closely observed as you are nearing due date. Take care and share your thoughts.
Avatar n tn This has nothing to do with the quality of the monitor, but the fact that an irregular heart rhythm will cause a variable cardiac stroke volume. Blood pressure monitors work by analyzing the variations in the pulse wave while air is released from the cuff. If the pulse waves are variable due to an irregular heart rhythm, the measuring can be wrong, especially the diastolic pressure.
Avatar n tn She can't seem to tolerate blood pressure medications in any dosage--it causes her blood pressure to drop extremely low. She has had all sorts of tests for her high blood pressure with no causes found. Are there any vitamin supplements or specific foods which could help regulate her blood pressure? Is there something she should or shouldn't do first thing in the morning? Something she should or shouldn't eat? The only other medication she is on is synthroid.
996946 tn?1503252712 When the heart beats very fast, such as during an episode of atrial fibrillation, it doesn't fill itself well leading to a decrease in stroke volume and cardiac output and a lower blood pressure (systolic). As a result your body then releases norepinephrine and other vasoactive hormones which act on the peripheral vasculature and cause the diastolic pressure to go up. Atrial fibrillation and high blood pressure are related.
Avatar n tn my mon has low hemoglobin, she is 82. Her level is at 8.6.. What is the best recomendation you can give me??
Avatar m tn Before taking Adderall Stop using Adderall and call your doctor at once if you have a serious side effect such as: fast, pounding, or uneven heartbeats; feeling light-headed, fainting; increased blood pressure (severe headache, blurred vision, trouble concentrating, chest pain, numbness, seizure); or tremor, restlessness, hallucinations, unusual behavior, or motor tics (muscle twitches).
Avatar n tn When medication(s) is properly administered there should be a reduction of heart rate and blood pressure, and it appears you are overdosed and it is surprising you still have high blood pressure and heart rate!!?. Another response, QUOTE: "A rapid heart rate with LOW blood pressure could be a sign of heart failure, but in your case, I would guess (I'm no doctor) that your heart is fine." Probably not revelant but what is the etiology of the comment?
11478709 tn?1526754875 Your skating sessions are presently likely causing lactic acid to build up to a level where it causes vasodilation ( blood vessels get dilated) so there's sustained higher blood flow, less blood volume in the heart, thus lower blood pressure. Also the increased heat generated by the exercise, causes dilation of blood vessels in turn as a compensatory mechanism to lower heat, this too contributes further to lowering blood pressure.
Avatar f tn Chances are, if you receive one that is significantly lower, than you’ve just done the calculations incorrectly. However, if the pulse pressure is genuinely low, it reflects a low stroke volume, which means your heart is not pumping out the amount of blood it is supposed to. This could be because of a very serious problem, such as congestive heart disorder or shock." Excerpt from "Pulse Pressure....The Other Blood Pressure!
Avatar m tn The cardiologist that reads the echo says its related to my high blood pressure.. again, I do not have high blood pressure and no one seems to listen. The strange thing is that high blood pressure is never mentioned in my records, and every time they take it for my office visit it is always in the normal range. My mitral valve is elongated and I understand that this may be the reason for the MR and the LAE. This is my question.
1124887 tn?1313758491 I know my heart is strong and pumps a lot of blood. Last echo revealed a stroke volume above 100 ml and an EF of 75-80%. I have a fairly slow resting heart rate (45-50 in the morning). I have some PACs but I've learned to live with them. What could be the reason? High stroke volume causing large pulse waves? Anxiety while measuring? (I tend to be a bit stressed and anxious to get the results). Stiff arteries (at my age)? Any thoughts?
487969 tn?1249316891 In its most basic sense, this can be viewed as a math problem--cardiac output = stroke volume x heart rate--except we don't know exactly what is affecting the stroke volume and/or heart rate to begin with...I'd venture a guess that it's our thyroids...but that's just me. :) Sorry if that was confusing; I'm just pleased to demonstrate that I learned something from the anatomy & physiology courses I took lol...
Avatar m tn They are cardiac output, peripheral resistance (degree of constriction would influence diastolic pressure) and stroke volume of blood. The contribution of the heart to the regulation of blood pressure is through changes in cardiac output. Cardiac output is defined as the product of heart rate and stroke volume. Either can be modified by climatic forces.
Avatar m tn If blood pressure increases, the kidneys increase their excretion of salt and water, so that blood volume decreases and blood pressure returns to normal. Conversely, if blood pressure decreases, the kidneys decrease their excretion of salt and water, so that blood volume increases and blood pressure returns to normal. The volume of fluids should not dilate vessels if kidneys are functioning properly. Exercising can/will dilate vessels.
Avatar m tn the same MAP regardless of if heart rate is 100 and stroke volume 100 ml, or the heart rate is 50 and stroke volume 200 ml, the same is not true for pulse pressure (sys minus dia). While the first might have a blood pressure of 140/90 and a MAP of 105 mmHg, the latter may have a blood pressure of 180/70 and the same MAP. Everyone have their unique stroke volume:pulse pressure ratio, depending on arterial compliance/stiffness. In general, a lower number may indicate higher arterial stiffness.
Avatar n tn I have been a pretty heavy exerciser for years. My blood pressure was running in the range of 145/90 and with the addition of Toprol it goes from about 110 over 70 to 115/75. Ill be interested in the answer. However from the beginning i noticed a "heavy leg" effect. Good luck!
Avatar n tn CO (volume of blood pumped with each heartbeat) there is a variation of volume of blood pumped with each stroke to maintain a balance between left and right side blood flow) and abviously PAP will vary accordingly (stronger heartbeat,higher PAP. If there are blockages (clots) in the lungs or pulmonary artery (increase of resistance the heart pumps against, and/or if there is narrowing, stiff pulmonary vessel the more resistance (increase of resistance will cause higher PAP).
Avatar f tn Boom!! stroke see ...,im scared and dunno how to relax ps. im 5'5.5 and 145-150 pounds..
Avatar m tn When my blood pressure is too high I feel bad and think that I will have a heart attack or a strokeand when my blood pressure is slow, I feel like I will faint, my pulse rate is higher and I feel bad also… it’s seem that I feel all the time bad cause of my heart… I’m a little bit frustrated cause the holter monitor will give normal results and my Cardiologist will call me and say I have nothing wrong BUT in fact I have a lot of weirds things who happen with my heart since a while… the chest
Avatar n tn After reading an article on postural orthostatic tachycardia syndrome, I discovered dehydration leads to low blood volume which causes low blood volume which lowers blood pressure and the heart increases rate significantly to supply blood to the entire body. BINGO! I immediately started drinking 2 liters water (distilled) in addition to my others liquids which were primarily limited to coffee, water with meds and exercise, and a few beers.
Avatar n tn I told her my concerns about my blood pressure / pulse pressure but she said she has never heard the term pulse pressure and the difference between them is irrelavant. Is it worth me going to see another GP to get another opinion?
255738 tn?1230236962 The pulse pressure is determined by the interaction of the stroke volume of the heart, compliance (ability to expand) of the aorta, and the resistance to flow in the arterial tree. By expanding under pressure, the aorta absorbs some of the force of the blood surge from the heart during a heartbeat.
Avatar m tn Pulse pressure (the difference between systolic blood pressure -- the pressure during contraction of the heart -- and diastolic blood pressure -- the pressure during relaxation of the heart) may be widened, and diastolic blood pressure may be low. There may be signs of pulmonary edema (fluid in the lungs. You are young, but you should get a physical exam to rule out medical problems. Take care. There is some general information at a thread with thisw forum in the archives: http://www.
Avatar n tn The sensation is as if my head and neck are throbbing with pressure and I have to stop walking or slow down and stop and stand still for a minute or so to make the sensation stop. Sounds are muffled in rhythm with the pulsations and I sometimes feel as if I will pass out, but never have. There is no pain. I have been checked throughly by my GP, a cardiologist, and an electrophysiologist and none of them could find a cause.
