Stroke volume for normal resting heart

Common Questions and Answers about Stroke volume for normal resting heart


Avatar f tn I am a healthy, fit, and very active 47 year old woman--healthy lifestyle and diet, runner, and I ride my bike for transportation. Resting HR of 52. PACs started a few weeks ago, so got a Holtor which reported over 4000 PACs/24 hours (that was half of what they had been previously), sleeping HR went as low as 41. Had an echocardiogram the other day, and everything was normal, except: "severely increased left atrial volume." Mysteriously, left atrial *size* (i.e., diameter) was normal.
Avatar n tn Heart rates, particularly during and after exercise, though, are also highly sensitive to a person’s hydration and nutrition status. Dehydration represents a state of diminished water supply in your body. Because circulating blood is composed of approximately 83 percent water, dehydration effectively lowers the amount of blood that your heart is able to circulate with one beat, or contraction. Your heart compensates for this low "water" volume by beating more times per minute.
1124887 tn?1313758491 EF is a compensating factor and helps maintain a balancing flow of blood between the right and left side of the heart. Stroke volume is inverse to the heart rate. Slow heart rate the greater the stroke volume which indicates the heart rate is also a compensating factor...the slower the heart rate the more time to fill. Wide pulse pressure (no medication, etc) can be the outcome of increased CO due to fitness, anxiety, hyperthyroidism, etc.
Avatar f tn It is just not fast enough to perfuse the body. Your cardiac output is your stroke volume times your heart rate. If your stroke volume is very high, but your heart rate is too low, your CO will still be too low for your body. This has to be checked by a doctor. Let us know how it goes.
Avatar n tn 25 mmHg or less, (yours is 20 with blood pressure of 97/70) the cause may be low stroke volume, as in Congestive Heart Failure and/or shock, a serious issue. This interpretation is reinforced if the resting heart rate is relatively rapid, e.g. 100-120 (in normal sinus rhythm), reflecting increased sympathetic nervous system activity. I'd suggest taking your BP and pulse for a few days at the same time and keep a log. If they show unusual go to doctors with them, something could be going on.

Avatar m tn the heart is stretching/thinning to achieve a higher stroke volume as it becomes harder to meet oxygen demand, which will eventually lead to enough wall thinning and stress (via volume overload and increased filling pressures) that it leads to systolic deterioration....
Avatar n tn Thanks for the input Ken. The only conflicating data with stroke volume being, even though I'm athletically conditioned by running, weight training, swimming, boxing etc... I still find that at rest, ie. lying on the couch and having a BPM of 50 and getting up and walking up a flight of stairs, my BPM will reach 120 within 3-4 seconds. I though an increase stroke volume will definatly result in a lower heart rate upon minimal exericse.
Avatar f tn 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.
Avatar n tn When I stop exercising my HR goes back to normal, I don't know what my resting heart rate is though. The next day I don't feel particularly sore. Is this normal? Some guy who saw my HR read out at the gym was convinced I was going to have a heart attack. I am almost 32 female, 5'3 125 lbs non smoker, been pretty active my whole life but would no consider myself to be in top shape.
Avatar f tn so he give me a 10 day event monitor where we finally figured out that I'm having pacs, he says theyou are harmless and no need to worry about them. My resting heart rate avgs between 50-60 which he said was good but with it being low it could be allowing the extra beats to fire off occasionally. I had blood work like 3 different times and everything come back good.
Avatar m tn Everyone get a high heart rate in the beginning of exercise (and it will slow after a minute or so) because it takes time to increase the stroke volume in the heart (it takes some time for enough blood to run back, to properly fill the heart). The heart compensates by increasing the heart rate. Again, with anxiety, the effect will be stronger. It's fairly normal that the heart rate drops quickly after this, but it can also be sustained high if the anxiety gets you.
Avatar n tn I was always told that my heart was in normal rhythm in spite of a high rate. My resting pulse is a bit lower now than prior to starting the drug but I apparently have adequate blood pressure as I am not dizzy etc. It is now about about 60 to 64. I simply cannot believe the change after so many years. I will keep using it and keep my spirits up that it will continue to control the condition as I slowly increase my training intensity. I don't want to overdo it too soon etc.
Avatar m tn Ejection fraction (Ef) is the fraction of the end-diastolic volume that is ejected with each beat; it is stroke volume divided by end-diastolic volume. Normal in a man is 50-68%. With a given sized ventricle and its volume, and its ability to contract, I fail to see how a faster or slower heart rate will affect the volume of blood leaving the chamber. If the heart pumps faster, the volume leaving the ventricle will always be the same.
Avatar m tn An athlete's heart muscle increases contractility strength...a resting heart rate can be less than 60 bpm. Top-level training is often associated with morphological changes in the heart, including increases in left ventricular chamber size, wall thickness, and mass. That is different from a normal dilated heart and an abnormal dilated heart (the increased size will decrease EF). You might want to average all estimated measurements, and that should be close to what is your functioning EF.
Avatar m tn Alberto Salazar a top class marathon runner out of Portland Oregon was some what of case study of a very conditioned heart years ago when his heart rate was in the 30'ish range. Normal for comparison is 60-100 bpm I completely doubt that your heart is so conditioned to have the stroke volume of a marathon runner, who incidentaly, his backup pacemaker was the predominant pacer. He was in a junctional rhythm. As far as your weight, at age 15, I was 185cm and 57.7kg.
Avatar n tn Today, when i got home from school i checked my heart rate, and it was around 100 beats per minute, after sitting and resting for a couple of minutes. This feeling of a high heart rate has bothered me throughout the day. I am also feeling some sort of pressure in the right center chest area which has been a bother to me as well. Other symptoms I feel are a slight dizziness and tiredness.
Avatar m tn I agree with Jon and to give you some insight: High blood pressure is anything above 120/80. However, mild elevations beyond those numbers only slightly increase the risk of significant health problems. But generally doctors don't prescribe medication to bring down blood pressure until the systolic reaches 140 or the diastolic reaches 90. The exception is for people with diabetes or impaired kidney function, and medication for anything above 130/80.
Avatar m tn It's usually 98 but it did go up to 101 at one time. My resting HR when I wake up in the morning is 60ish and my normal heart rate at mid-day is 80. It goes down in the 70's at night. Adderall seems to effect my HR 4-6 hours a day. It might be raising blood pressure as well (more on this in a sec). I live pretty unhealthy. I don't exercise and I eat way too much junk food. My maternal side of the family also has a history of heart disease.
Avatar m tn If you aren't highly athletic, mid 30's is probably lower than desired. Athlete's get slower beats because their stroke volume is greater than normal. According to wikipedia (see Bradycardia article), some healthy athletes have had rates as low as 27bpm. The wiki article outlines several possible causes, but I think your intuition about age is leading you towards the most likely diagnosis.
Avatar n tn I try to keep my activities as less as possible to reduce work load on my heart except for 30-40 minutes when I go for a walk when my pulse reaches 90-100 bpm. Otherwise it is mostly 60-70. I recently read a post on this forum which says that with EF 30-35% life expectancy can be aroung 5 years. I have already completed 3.5 years.Anything else I can do to improve or keep my EF stable?
Avatar n tn Because of another condition I am up every 2 hr or so (bladder condition), so the nights are pretty much a 'nightmare' these days. They say heart function is normal, I have been off caffeine for 3 weeks, and they started to get better untill I had to have antibiotics for a week....back to square one! But I will stay off the caffeine, and see what happens. Crossing fingers that it will happen like last time and eventually I can have a cup of coffee again (even decaf affects me).
1298588 tn?1330322581 Weight lifting is increasing the blood pressure without increasing the heart rate and stroke volume so much. For that reason, weightlifters get a hypertrophic heart. People with chronic rapid heart rate can get a dilated heart. People doing aerobic exercise like runners, will get an athletes heart, which is both slightly dilated and hypertrophied (it grows both ways). This is healthy (within reasonable limits). The other two are not.
Avatar m tn He also didn't want me to take any other tests since I had a stress test 2 years prior which was normal. I am now waiting to see another cardiologist for a second opinion. My normal resting heart rate is about 44/50 but never when moving.
748543 tn?1463449675 For the past few weeks I have been throwing around ideas as to the best way to respond to this matter. You see a recent article ( Feb.3 , 2009 NY times) titled "Best treatment for TMJ May be Nothing" nearly made me clench my jaw to pieces. While well written, I found that the author, Ms. Brody, relied heavily on out dated and narrow perspective supplied to her by a small group of dentists.
Avatar n tn I've had problems with tachycardia and palpitations for about 20 years ( i'm amost 50, post menopausal, normal weight). I've had several heart event monitors ( last for 2 weeks in December), holters, stress tests, echos, the works. Years ago it was "MVP";over the past several years i was told I don't have that, maybe a little reentry problem and inappropriate sinus tach, nothing life threatening.
Avatar m tn More important here would be resting blood pressure, symptoms, exercise capacity etc. All of which are normal for you. Your elevated decel time is important but your resting heart rate in addition to all the other diastolic factors, e/a, e/e' ivrt, a wave reversal, LA Volume etc. All need to be considered. When combined these factors will determine the best course of treatment (if any).
Avatar n tn Hi Esther Yes, very normal for metoo and I am sure many others. I get bouts of rapid heart beating and feeling that my heart is skipping a beat or two and chest pains. I too went to the Doctors this time last year he did and E.C.G which was fine.He did put me on Pantoprazole 20 mg for acid stomach, even though I would not have said that I had a problem with that but they seem to have helped. Just last week while at work it happend again .
Avatar n tn The only way I know of to lower resting heartrate is to strengthen your heart through exercise (it improves the efficiency of your muscles including the heart and also increases the stroke volume of the heart so that you pump more blood with every beat) but I don't know how issues like age, heart disease etc affect that process.
Avatar m tn CO is a product of blood volume per heart stroke and heart rate. The higher/better the stroke volume (weak, strong, stronger contractions) the fewer heart beats (more for weak, less for strong, least for stronger) are required to meet demand (held constant for illustration) for blood oxygen. A well-condition individual requires fewer heartbeats due to strong contractions. It is the stroke that determines EF...not the CO, as CO can vary by an increase or decrease of HR.
