Relation between cyclic variation in echo amplitude and segmental contraction in normal and abnormal hearts.
OBJECTIVE--To study the relation between cardiac systolic activity and cardiac cycle dependent variation in the ultrasound signal arising from within the myocardium. DESIGN--Regional echo amplitude was used as a measure of the myocardial ultrasound signal. Relative echo amplitude values were assigne...
