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 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 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 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 Some enlargement is expected if you are quite fit. The more intense the exercise regime, the more the heart will naturally adapt, up to a limit. This is why athletes hearts can pump blood so much more efficiently around the body. The heart muscle increases and the internal volume increases, allowing more blood to be pushed out with each stroke.
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.
2175879 tn?1338355028 My MRI results came in. This time my neurologist actually found proof that I had a stroke. First they thought it was a TIA, then an ear ache, and then I kinda forced the issue, they did another MRI and actually found a small "disruption" on my right side of my brain. I can't tell you how relieved that makes me.
Avatar n tn I am in the UK. I was very, very fit, ran, lived at the gym, windsurfed & kart raced. I had a very, very bad stroke in March 04, I was 42. I nearly died, which is an effect! Lol. Now in a wheelchair, speach is very, very bad & I am virtually paralysed. I wrote a 68,000 word book, which I cannot advertise here. Doctors said I would just have eye movement. I believe I am still recovering. Tim.
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.
