And a method for non-invasive evaluation of system parameters and cardiac tissue

摘要

System and method for noninvasive assessment of cardiac parameters and characteristics of the cardiac tissue using ultrasound techniques is disclosed. If the atrial pressure contractility of the myocardium, infarction and myocardial ischemia, and the filling of the ventricle, and the measured value tissue stiffness of the myocardium, tension, strain, strain rate and the like is used to assess diastolic function there. Used for acoustic techniques, such as ultrasound to collect data related to specific tissue displacement, non-invasive system is disclosed. Ultrasonic techniques may be used to induce the cardiac tissue site response for cardiac parameters and / or characteristics of the cardiac tissue or approached or stimulated acoustically cardiac tissue, non-invasive system is also disclosed.
