[Left ventricular regional kinetics. Comparative analysis of the reference systems, correlations and physiological considerations].
The AA. studied segmental wall motion of the LV by means of 7 different methods. The study was performed in order to determine which reference system is the best for utilizing in subjects not affected by any heart disease. Two interesting points have emerged: first the methods which utilise the gravity center are the most sensitive; second, LV wall motion depends on the ejection fraction. In this perspective the AA. present a model of left ventricular motion.
