Final answer:
In significant aortic insufficiency, septal motion often demonstrates exaggerated early diastolic dip.
Step-by-step explanation:
In significant aortic insufficiency, septal motion often demonstrates exaggerated early diastolic dip. During the early phase of ventricular diastole, the pressure within the ventricles drops below the pressure in the aorta, causing blood to flow back toward the heart. This results in a small dip in the blood pressure tracings, known as the dicrotic notch. This is seen in patients with aortic insufficiency due to the backflow of blood into the left ventricle during diastole.
