[Possibility of the thermographic method for detection of ischemic myocardium].

Thermography (TG) is used as a contact free method for investigation of the myocardium ischemic injury. In coronary bypass surgery without artificial blood circulation it is important to know how cessation of blood supply affects the myocardium. In experiments on working heart, TG allows monitoring temperature at the desired point of the epicardium.

[Effects of cardioelectrostimulation and chemical preparations on autonomic nervous regulation of heart rate].

The aim of the study was to evaluate the peculiarities of heart rate variability and autonomic nervous system regulation and to predict the changes in sinus rhythm after successful medical or electrical correction. 72 patients with atrial fibrillation before and after its correction have been monitored. Atrial fibrillation during the first month after cardioversion occurred in 26.

[The effect of calypsol, thiopental sodium and fentanyl on the functional status of the sinoatrial node and the heart conduction system in patients with paroxysmal arrhythmias].

64 patients with paroxysmal arrhythmias caused in 44 cases by collateral atrioventricular pathways have been studied. Endocardial programmed electrical cardiostimulation was applied. It has been established that calypsol at a dose of 2 mg/kg significantly improves the functional state of the sinoatrial node, atrioventricular conduction and conduction in collateral atrioventricular pathways functioning both anterogradely and retrogradely.

Cryosurgical ablation of right parietal and septal accessory atrioventricular connections without the use of extracorporeal circulation. A new surgical technique.

A new technique for definitive surgical treatment of the preexcitation syndrome without the use of extracorporeal circulation has been elaborated and clinically used in 25 patients with Wolff-Parkinson-White syndrome. Seventeen patients had right parietal accessory atrioventricular connections and eight had septal connections. In patients with right-sided connections the fat pad in the coronary sulcus was dissected with an ultrasonic scalpel.
