akinetic wall motion
Complete absence of myocardial wall movement during cardiac contraction as seen on echocardiography.
Full Definition
Akinetic wall motion refers to the complete absence of myocardial wall movement during systolic contraction, indicating severe myocardial dysfunction or necrosis. This finding is typically observed on echocardiography during acute coronary syndromes and represents non-viable myocardium. Wall motion abnormalities are graded from normal (normokinetic) to hypokinetic, akinetic, and dyskinetic. The presence of akinetic segments helps clinicians assess the extent of myocardial damage and guide treatment decisions.
Usage
Usage note: Always specify the anatomical location when describing akinetic segments.
