Abstract
Some heart diseases, such as cardiomyopathy, myocardial infarction, and others, are accompanied by myocardial damage. When advanced diagnostic equipment is employed in the clinical examination of a patient with myocardial damage, intensified abnormal echoes, at the damaged myocardial area, are frequently observed. Figure 13.1 shows two dimensional echocardiograms taken from a case with hypertrophic cardiomyopathy(HCM). Abnormal strong speckle-like echoes are seen in the area of the left ventricle. However, the mechanisms responsible for the occurrence of these echoes remain obscure.1)
