[Approximation of mathematical scanning simulation data and clinical results f radiofrequency ablation of perimitral atrial flutter. Condition of existence of perimitral atrial flutter].

Aim: 1) to create Perimitral Atrial Flutter (PMAFL) model and estimate theoretical probability of elimination of perimital reetntry using left atrial geometry two-dimensional mathematical modeling and ablative formatting; 2) to compare clinical results of PMAFL ablation by means of mitral vs inferioseptal isthmus ablation and mathematical modeling data.

Material And Methods: Clinical phase. Study was conducted on 24 pts (6 women, 57.

[Comparison of the effectiveness of pulmonary veins isolation vs linear radiofrequency ablation in paroxysmal atrial fibrillation patients using either mathematical scanning or clinical approach].

Aim: to compare clinical results of linear ablation vs. PVI approach in patients with paroxysmal AF and to estimate theoretical probability of 4-waves re-entry to eliminate as a results of the both ablative techniques formatting by means left atrial geometry two-dimensional mathematical modeling.

Material And Methods: Clinical phase.

[Hemochromatosis: the clinical picture, diagnosis and treatment].

A survey of literature data and the author's own observation of 18 patients with hemochromatosis (H) have shown that H is a polysyndrome disease. Men aged 35 to 60 suffer more frequently. Its most significant symptoms and syndromes are skin hyperpigmentation, hypersideremia, liver cirrhosis, diabetes, cardiomyopathy, and endocrinopathy.

[Functional status of the thyroid gland and blood cholesterol levels of donors].

The levels of protein-bound iodine (PBI), cholesterol, F factor, thyroxine (T4) and triiodothyronine (T3) were studied by a radioimmunoassay in the blood serum of 204 workers and employees (128 males and 76 females) as primary donors and 146 experienced donors (84 males and 62 females) aged 18 to 59 in the city of Frunze. In the primary donors PBI, cholesterol, F factor, T4 and T3 levels in the blood serum were within normal for healthy persons. In the experienced donors T3 and T4 levels in the blood were significantly elevated and a cholesterol level was lowered suggesting an increase in thyroid function.
