[Diagnostic potentials of echocardiography and ultrasonic scanning in ischemic heart disease]

Single-chamber echocardiography and B-scanning provide for evaluation of the local and total left ventricular function in patients with ischemic heart disease. In cases with zones of asynergy, B-scanning may be applied for quantitative evaluation of left ventricular volumes, the diagnosis of left ventricular aneurysm, appraisal of the extent of the zone of myocardial affection, and the contraction geometry and overall function of the left ventricle; the data yielded by echocardiography in the M-method are less accurate and less reliable.
