Question

In significant chronic aortic insufficiency, M-mode/two-dimensional evidence includes all the following EXCEPT:

A. Hyperkinesis of the interventricular septum
B. Hyperkinesis of the posterior wall of the left ventricle
C. Left ventricular dilatation
D. Paradoxical interventricular septal motion

Answer 1

In significant chronic aortic insufficiency, M-mode/two-dimensional evidence includes hyperkinesis of the interventricular septum, hyperkinesis of the posterior wall of the left ventricle, left ventricular dilatation, and paradoxical interventricular septal motion.

Step-by-step explanation:

In significant chronic aortic insufficiency, M-mode/two-dimensional evidence usually shows:

1. Hyperkinesis of the interventricular septum
2. Hyperkinesis of the posterior wall of the left ventricle
3. Left ventricular dilatation
4. Paradoxical interventricular septal motion

Therefore, the answer to the question is none of the options: A. Hyperkinesis of the interventricular septum, B. Hyperkinesis of the posterior wall of the left ventricle, C. Left ventricular dilatation, or D. Paradoxical interventricular septal motion is excluded in M-mode/two-dimensional evidence of significant chronic aortic insufficiency.
