ABSTRACT
The study includes 45 patients with ischemic heart disease. The reproducibility of Selvester's QRS-point index was examined by two researchers (r = 0.98). Between the ejection fraction of the left ventricle and the ECG-pont indices there exists a reverse relation, the correlation coefficients being equal (r = -5.58). Between the segmental disturbances of the left ventricular wall movements, examined by the systolic shortening in percentage of the radial axes, and both ECG indices there is also an equal correlation (r = 0.59). The relation between the angiographically evaluated segmental disturbances and the ejection fraction is also reverse, r = -0.88. The results of the study prove the relatively great possibility for mistakes of only the routine rest ECG is analyzed. The ECG evaluation of the left ventricular function cannot disclose the compensatory reserves of the healthy myocardium.

84 persons were examined: 61 patients with rheumatic mitral valve stenosis (21 men and 40 women), mean age 39.38 +/- 11.2 years and 23 healthy controls (14 men and 9 women), mean age 25.62 +/- 3.8 years. The morphologic and quantitative characteristics of the diastolic part of the pulse Doppler echocardiographic signal of mitral circulation analyzed by histogram of the time intervals show highly significant statistical differences between the patients with mitral valve stenosis and the healthy controls (100% specificity and sensitivity). The differentiation of mild and moderate from severe mitral stenosis by pulse Doppler echocardiography of mitral valve circulation, analyzed by histogram of the time intervals, is achieved with satisfactory precision by determination of the speed of the circulation fall in the early 1/3 of the diastole. The pulse Doppler echocardiograph performed by a transducer with 2.5 mHz frequency and the simultaneous M-echocardiography, the Doppler effect being analyzed by histogram of the time intervals, do not allow the precise determination of the degree of mitral valve stenosis.

10 healthy persons were examined by two left ventriculographies--conventional and hemiaxial. The results show good and exceptionally good reproducibility (r = 0.80 up to 0.90) of the quantitative indices for global left ventricular function in all projections with the exception of the end systolic volume index of the left ventricule in the cranial left anterior oblique projection (r = 0.67) and of the ejection fraction in the left oblique projections (r = 0.6 and 0.68). The results of the segmental analysis of the left ventricular wall movements show good reproducibility in the four projections (p greater than 0.1) in spite of the fact that the models used depend on the exact determination of the cardiac apex.

34 patients with myocardial hypertrophy, mean age 44 years, were examined by two-dimensional echocardiography and the degree of disproportion of the hypertrophy of the different left ventricular segments was analyzed. Besides the classic index--ratio between the septum and the posterior ventricular wall--a new index for the asymmetry of the hypertrophic process is proposed: the ratio between the thickest, segment and the thinnest segment. The new index is more sensitive in determining the asymmetrical hypertrophy.

The authors studied the therapeutic effect of lidocainee peroral forms in case of rhythm disorders, accompanying with various cardiac diseases. The results obtained revealed that in 76 per cent of the cases with ventricular extrasystoles, the treatment result was very good, with complete disappearing of extrasystoles. Good effect was found in 18 per cent, with the recording of some rare, single extrasystoles towards the end of the treatment, and the treatment had no effect on 6 per cent of the patients. The drug proved to be effective in the cases with supraventricular extrasystoles. Lasting result was attained in 89.36 per cent of the patients treated. Due to the favourable therapeutic effect and good tolerance the authors recommended lidocain peroral form for wide application in the treatment of rhythm disorders.
