Discusses the historical development and challenges of using echocardiography to quantitatively assess left ventricular pump function.
Since the development of ultrasound as a clinical means to observe intracardiac motion, echocardiographers have been enticed by their ability to see sluggish wall motion of the failing left ventricle compared with vigorous wall motion in the normal or volume overloaded ventricle. The extremes are obvious by this technic, leading one to expect that quantitative methods can be used to define the spectrum between the extremes. Efforts to assess left ventricular pump function have been partially frustrated by the approaches taken toward recording ventricular-wall motion by conventional echocardiography. The sound beam can be likened to a flashlight aimed through the . . .
