RESUMEN
AIM: To analyse the results of using transesophageal pacing (TEP) for correction of atrial fibrillation of type I (AF). MATERIAL AND METHODS: The study included 1283 patients with coronary heart disease (CHD) and newly diagnosed AF. All the patients were examined with transthoracic echocardiography, received basic antianginal treatment. AF was corrected with TEP. RESULTS: Sinus rhythm was reestablished in 83.48% patients, in 67.33% TEP was made without previous antiarrhythmic therapy, in the rest patients with this pretreatment. The best result was observed in pre-pacing administration of amiodaron or its combination with hinidin-durules. Only 2.88% patients retained AF after TEP. CONCLUSION: TEP is an effective method of type I AF treatment.

AIM: To ascertain optimal antiarrhythmic therapy (AAT) in paroxysms of atrial fibrillation (AF) and atrial flutter (AFl) basing on their pretreatment duration. MATERIALS AND METHODS: A total of 2851 coronary heart disease (CHD) patients with AF and AFl paroxysms aged 40-75 years were treated from 1982 to 1996. The patients received sublingual or oral drugs (anaprilin, ethacizine, quinidine, etc.) or intravenous antiarrhythmic drugs (ritmilen, isoptin, novocainamide, etc). RESULTS: In pretreatment duration of AF and AFl up to 3 hours more pronounced effect was observed with sublingual and intravenous antiarrhythmic drugs. In the paroxysm duration up to 6 days, maximal antiarrhythmic effectiveness occurred in the use of intravenous antiarrhythmic drugs or quinidine, quinidine + verapamil. In the paroxysm duration from 7 days to several months, positive effect was achieved only in administration of quinidine or quinidine + verapamil. CONCLUSION: The principle of differentiated therapy of AF and AFl in CHD patients depending on the paroxysm duration before treatment allows choice of adequate therapy by enhancing its antiarrhythmic and weakening arrhythmogenic effects.
