Cardiac Elastography is a new technique to analyze strain and strain rates in many organ systems, including the heart. In this study, cardiac elastography derived from analysis of raw radiofrequency data obtained form a conventional clinical echocardiograph system will be conpared to processed infromation that comes from the same echocardiograph system. The purpose of this study is to determine if cardiac elastography can accurately deteremine strain and strain rate as compared to more conventional means.
