Echocardiographic apparatus for myocardial disease diagnosis by A-wave quantification

摘要

A-wave quantification indicator automatically measures the difference in amplitude between the peak of the E-wave portion of an ultrasonically derived M-wave CRT display and the peak of the A wave portion of the M-wave. This difference in amplitude, which distinguishes myocardial-disease and hyperkinetic syndrome subjects from normal subjects, is alphanumerically displayed in quantitative and/or qualitative terms.
