[Assessment of the use of various cardiac pacing modes for selection of antiarrhythmic therapy for prevention of recurrent attacks of atrial fibrillation and flutter].

Aim: To determine optimal mode of transesophageal pacing for selection of appropriate antiarrhythmic therapy for prevention of attacks of atrial fibrillation and flutter in patients with ischemic heart disease.

Material And Methods: Two hundred eighteen patients with ischemic heart disease and attacks of atrial fibrillation or flutter. Selection of antiarrhythmic drugs was carried out with the use of competitive, rapid, salvos of ultra rapid, and slowly accelerating ultra rapid modes of pacing.

[Sinus node functions, sinoatrial conduction, atrial conductivity after incipient paroxysms of atrial fibrillation and flutter in patients with ischemic heart disease].

Aim: Prediction of the rate of recurrent paroxysms of atrial fibrillation (AF) and flutter (AFl) after the first arrhythmia episode; determination of relevant antiarrhythmic treatment.

Material And Methods: 157 patients with ischemic heart disease (IHD) complicated by new episodes of AF and AFl entered the study. After the initial episode and 1-2 arrhythmia recurrences all the patients have undergone assessment of hemodynamics, atrial conduction of excitation, sinus node function using transesophageal pacing.

[Various regimes of cardiostimulation in determination of anti-recurrence therapy of atrial fibrillation and flutter paroxysms in patients with ischemic heart disease].

Aim: Choice of optimal cardiostimulation regimens using transesophageal pacing for design of antirecurrence antiarrhythmic therapy (AAT) in IHD patients.

Material And Methods: 198 patients with IHD complicated by paroxysms of atrial fibrillation (AF) and atrial flutter (AFl) received AAT chosen at concurrent, frequent, volley UHF and slowly increasing UHF stimulation using transesophageal pacing.

Results: Slowly increasing UHF stimulation proved most effective both in detection and reproduction of induced paroxysms of AF and AFl.

[The role of monoclonal antibodies to Venezuelan equine encephalomyelitis virus in specific activation of immunocompetent cells].

Effects of rabbit monoclonal antiviral antibodies on the function of splenic cells at passive immunization of animals was studied. A reliable increase of stimulation index was observed at in vitro activation of BALB/c murine splenocytes with Venezuelan equine encephalomyelitis virus, the mice being passively immunized with rat monoclonal antibodies 8D2, 3G1, and 5E7.
