Final answer:
Qualitative assessment of segmental wall motion on echocardiography involves evaluating the movement of different segments of the cardiac walls to determine abnormalities or dysfunction.
Step-by-step explanation:
Qualitative assessment of segmental wall motion on echocardiography involves evaluating the movement of different segments of the cardiac walls to determine if there are any abnormalities or dysfunction.
The assessment can be done by analyzing the contraction and relaxation patterns of different segments of the heart during systole and diastole. A normal segment will have coordinated and synchronized motion, while an abnormal segment may have reduced or delayed motion.
For example, a segment with hypokinesis will show reduced contraction compared to other segments, while akinesis represents a segment with no movement at all. Hyperkinesis, on the other hand, refers to excessive movement of a segment.
