The method of two-dimensional stress echocardiography with transesophageal atrial electrostimulation was used for determination of patients with high risk of complications among those who had survived myocardial infarction. The results of the test were compared to the degree of the coronary artery lesion. The highest sensitivity of the method (94%) in(More)
In most patients who had suffered from myocardial infarction 3 1/2 to 12 months (7.6 months on the average) previously and had no clinical symptoms of circulatory insufficiency, ultrasonic scanning of the heart showed normal stroke volume and stroke index, and normal minute volume and cardiac index against the background of low indices of left ventricular(More)
To study the possibilities of two-dimensional echocardiography (2EchoCG) in evaluating total and regional left ventricular contractility using computerized quantification as compared to biplane contrast ventriculography (CVG) 50 subjects were examined. There was a good correlation between the values of the end-diastolic and end-systolic volumes and the(More)
The effect of intravenously injected nitroglycerin on the left ventricular contractile function was studied in 17 patients during the first day of transmural myocardial infarction using uni- and two-dimensional ultrasound technique. The data obtained demonstrated a positive time course of some of the main characteristics of the left ventricular contractile(More)
Myocardial asynergic area was estimated, using a new special mathematical model based on computerized assessment of echocardiographic images, in 42 patients with first acute transmural myocardial infarction. The results were compared with those of other standard methods used for the estimation of the size of damage, and with morphologic findings in 7 fatal(More)
