Question

Repeat 2D echocardiography, although often performed for the reassessment of LV function, is not a sensitive or reliable tool for this purpose. The 95% confidence intervals for EF are ±(1)% and those for LVM are ±(2)g.

Answer 1

2D echocardiography is not a sensitive or reliable tool for reassessing left ventricular function. The 95% confidence intervals for ejection fraction (EF) and left ventricular mass (LVM) give the range in which the true values are likely to fall.

Step-by-step explanation:

2D echocardiography is a technique used to assess the function of the left ventricle (LV) of the heart. However, it is not considered a sensitive or reliable tool for this purpose. The 95% confidence intervals for ejection fraction (EF) are ±(1)% and for left ventricular mass (LVM) are ±(2)g. These intervals indicate the range in which the true values of EF and LVM are likely to fall.
