Webb1 aug. 1996 · Background Three-dimensional echocardiography is a promising technique for calculation of left ventricular ejection fraction, because it allows its measurement without geometric assumptions. However, few data exist that study its reproducibility and accuracy in patients. Methods and Results Twenty-five patients underwent radionuclide … WebbObjective: To investigate the value of Simpson's rule, Teichholz's formula, and recording of mitral ring motion in assessing left ventricular ejection fraction (EF) in patients with left …
How can I measure the LV volume using the Simpson method?
WebbDie Ejektionsfraktion ist einfach zu berechnen. Wenn der linke Ventrikel am Ende der Diastole 100 ml Blut enthält und während der Systole 40 ml herausgepumpt werden, beträgt die Ejektionsfraktion 40%. Die Ejektionsfraktion ist also das Schlagvolumen (SV) dividiert durch das enddiastolischen Volumen (EDV): EF (%) = (SV/EDV)·100. Webb8 sep. 2014 · Inter-method repeatability was calculated by intra-class correlation coefficients (ICC) and agreement evaluated by Bland Altman plots. Results All measurements were obtained in all cases and showed ICC for left ejection fraction of 0.90 (95% confidence interval (95% CI) 0.78-0.95) and ICC of 0.90 (95% CI 0.80-0.96) for right … time waiver gratis
