Left Ventricular Volume During Maximal Supine Exercise:
Changes in left ventricular (LV) volumes and ejection fraction between rest and maximal supine exercise were evaluated in 11 patients who had had four epicardial markers placed during coronary artery surgery. After calibrating marker distances with respect to volume (r = 0.92-0.99) over one cardiac cycle for each patient, regression equations were used to compute LV volume from marker measureme...
متن کاملEchocardiographic assessment of left ventricular function.
The concept of "normalized velocity" has been applied in this study to the echocardiographic (echo) assessment of left ventricular (LV) function in 87 patients. The following normalized velocities were calculated from the ultrasound recording of LV wall motion: 1) the mean circumferential fiber shortening rate (mean VCF), 2) the mean normalized posterior wall velocity (Vpw), and 3) the mean nor...
متن کاملEchocardiographic Assessment of Left Ventricular Diastolic Function
J Echocardiogr Vol.6, No.3, 2008 57 The concepts for the assessment of left ventricular (LV) diastolic function were established in the cardiac catheterization laboratory and necessitate the use of high fidelity pressure and conductance catheters. The most recent [1] set of criteria (Figure 1) for diagnosing diastolic heart failure (DHF) include the presence of increased LV filling pressures (m...

Extended abstract Echocardiographic Evaluation of Left Ventricular Function and Geometry in Pediatric Patients with Kidney Transplantation Cardiovascular disease (CVD) is an important, leading cause of mortality and morbidity in patients with chronic kidney disease (CKD) as well as in renal transplant recipients. Cardiovascular complications become more important in children because of the i...
متن کاملEffect of Supine Exercise on Left Ventricular
RESPONSE to physical exercise in man has been studied extensively. For any given workload, a predictable change in blood pressure, heart rate, and cardiac output has been shown to occur. Rushmerl has pointed out that the response of stroke volume to exercise, however, may be variable both in experimental animals and in man. He has also demonstrated that not only the amount, but also the directi...
