title: [Comparison between one and two dimensional echocardiography in the study of segmentary kinetics of the left ventricle in post-infarct ischemic myocardiopathy].
abstract: Sixty two-dimensional M-mode echocardiograms of myocardial infarction patients, performed 3--6 months after acute attack, were compared with those of 30 normal subjects. In one-dimensional echocardiograms, the dimensions of the left ventricle and some segmentary signs of contractility such as diastolic thickness, excursion and systolic thickening of the septum and the posterior wall of the left ventricle were examined, in two-dimensional echocardiograms the contractility of single areas was compared to those adjacent. In heart attack patients parameters studied were changed in a statistically significant way (p less than 0,001); the degree of correlation between the site of hypo-akinesis and the ECG necrosis site was quite high; compensatory hyperkinesia was frequently found in the area diametrically opposite to dyskinetic areas. The two-dimensional examination was also very sensitive especially in the diagnosis of aneurysm, which is sometimes not noted in M-mode.
