Stroke volume training

Common Questions and Answers about Stroke volume training

stroke

Avatar m tn Over many, many years, with high blood pressure and being very overweight, the inside of your ventrical gets thicker, and the volume inside therefore decreases, decreasing stroke volume and causing your heart rate to become higher and your heart then has to work harder to pump the same amount of blood, which over many years causes the ventricular walls to stiffen. I hope that clarifies some of it.
Avatar m tn 8cm systolic diameter, 22% FS, 117ml diastolic volume, 56.2 ml systolic volume, EF% 52, Stroke Volume 60.8, LVPW thickness .82cm, IVP thickness .88 So, my questions are the following: -Can you have some form of systolic dysfunction without ending up with an enlarged heart or an EF% lower than 50? -Could I have systolic dysfunction that is being controlled by my exercise, which is why I have been able to have an EF% in the low 50’s and no structural remodeling?
Avatar n tn I had a cardiopulmonary exercise stress test and went back for the results, I had gotten info from you re the VO2max numbers so I could try to understand what the doctor would tell me, instead the doctor said they measured the stroke volume and mine was "16" which he thought was low, what does this 16 mean, what would an average number be for a 55 year old female?
Avatar n tn You can't measure stroke volume with the heart rate. Stroke volume is the amount of blood that your left ventricle pumps out with each heart beat. If you multiply the stroke volume by the heart rate you get your cardiac output.

Avatar n tn I recently began a training program with a significant higher volume of training than the past 7-8 years. My issue is that when I am at rest, periodically I can feel a significant thumping in my chest. I understand that for my resting heart rate to remain so low I have a high stroke volume. I just had a full medical evaluation from my employer and I have no other medical concerns. I do not take any meds, my BP is 110/70. I am 6ft, 196# with 18% body fat.
Avatar n tn i had a echocardiogam which shows that my stroke volume is 47 ml is it a normal value or it is a sign of heart failure.all other things are normal in my echo. my ejection fraction is 61.4%.
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.
1124887 tn?1313754891 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 n tn i have been suffering from shortness of breath for 5 months.recently i have a echocardiogram. it shows that my stroke volume is 47 ml . is this is a normal value or it is a sign of a heart disease? my ef is 61%.
Avatar n tn Since than I also had a muga test done which showed no change in my stroke volume at rest and during exercise. Currently I have a echo done every 6 months. My last echo was on 12/10/98 which showed that my heart has grew slightly from the last echo. My cardiologist has just prescribed medication which I think is Vazotec. I am currently very active with both aerobic and weight training activity. I am not experiencing any symptoms at this time. My blood pressure is 130/50.
Avatar f tn AF is not acutely dangerous but you do want to maintain the aspirin per the doctors instruction to reduce the risk of a stroke for now and ask the doctor about switching to anti-coagulation meds. Because yours is paroxysmal AF, it is hard to correlate it to anything else including strep. For some people, there are triggers such as caffeine, alcohol, hormonal changes, etc ... Also, endurance training could trigger remodeling of heart muscles and some will develop AF from excessive training.
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 In a pilot investigation of the effects of Lokomat, the researchers studied 30 stroke survivors who were randomly assigned to 30 minutes of robotic treadmill training and 30 minutes of conventional physiotherapy daily, or two 30-minute sessions of conventional physiotherapy daily. The researchers note that comparison with conventional treadmill training was not possible. After 4 weeks, both groups achieved a significant and similar improvement in walking ability.
Avatar m tn This happens by a system of vasodilation and vasoconstriction coupled with the pumping rate and stroke volume of the heart. Rather than make frequent changes in volume, the body changes the configuration of the total container (all the vessels) and increases the speed at which the resource is renewed.
Avatar m tn A faster heartbeat does not provide enough time to fill as at rest, and the timing of contractions are less. The percent of blood pumped with each heartbeat is less reducing stroke volume (lower EF). The heart rate has increased to provide the necessary blood/oxygen to meet the system's demand for the diminished stroke volume. The CT scan indicates there is substanital soft plaque buildup within the linings of the vessels.
1591333 tn?1297733419 These mechanisms would be interrrelated. The low blood supply (volume in circulation) the kidneys will increase the volume (an example would blood loss, or a low cardiac output). The left venticle will dilate to increase blood flow with each stroke and the heart rate will increase the cardiac output (amount of blood pumped per minute). If the system is dysfunctional, medication, etc. can change the dynamics.
