[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 duration of positive clinical effect of antirecurrence AAT of AF and AFl paroxysms in IHD patients determined at using this regimen of cardiostimulation averaged 3.1 +/- 0.3 years. Left atrial dilatation is an unfavorable prognostic criterion in respect to efficacy of the recurrence AAT.

CONCLUSION

Slowly increasing UHF stimulation is most effective in determination of antirecurrence AAT of AF and AFl paroxysms in IHD patients.
