From: What is the lowest change in cardiac output that transthoracic echocardiography can detect?
Intra-examination precision according to the number of measurements averaged within one transthoracic echocardiography examination. Data are expressed as median and interquartile ranges. *p < 0.05 sinus rhythm vs. atrial fibrillation. Solid lines indicate patients in sinus rhythm (n = 84). Dashed lines indicate patients with atrial fibrillation (n = 16). E/e’ ratio, ratio of the early peak velocity of transmitral flow over the early diastolic peak velocity of the lateral mitral annulus; LVEF, left ventricular ejection fraction; RVEDA/LVEDA ratio, ratio of the end-diastolic right over left ventricular areas; TAPSE, tricuspid annular plane systolic excursion; VTI, velocity-time integral
