Intracardial electrophysiological examination was conducted in 50 patients with suspicious or confirmed data about disturbed function of sinus node--namely: short-term auricular stimulation for determination of sinoatrial time (SAT) and long-term auricular stimulation with increasing frequency with analysis of the phenomena in the post-stimulation(More)
The changes in hemodynamics in conditions of dosed loading prior to and post cardioversion were followed up in 21 patients with valvular defects or atherosclerotic myocardiosclerosis and absolute arrhythmia with auricular fibrillation. In conditions of auricular fibrillation all the patients showed data about a deteriorated ventricular function (increased(More)
The potentialitis of the standard electrocardiogram, precordial cartogram and spatial analysis are confronted in 38 patients with extensive anterior or anteroseptal myocardial infarction, acute phase, in order to determine the extent and propagation of the myocardial hypoxia. The determination is performed on the base of the correlation dependence as(More)
200 patients (181 men and 19 women) with stable stenocardia were examined by the exercise tolerance test. The patients were loaded by the step by step method on veloergometer or threadmill up to 80% of the maximal pulse rate. 126 of the tests were evaluated as positive. False positive were 10 tests and 19 tests were false negative. The coefficient of(More)
In 216 patients with right ventricular cardiac overload the changes of 76 electrophysiological indices were studied--indices of the corrected orthogonal electrocardiogram after Frank, corrected orthogonal vectorcardiogram, spatial electrocardiogram and high-speed spatial electrocardiogram. The patients with right ventricular cardiac overload are divided(More)
