  • Title: [Efficacy of frequent electrostimulation of the left atrium via the esophagus to stop atrial flutter].

    Journal: Kardiologiia; 1984 Dec; 24(12):18-22. PubMed ID: 6521219.
    Abstract:
    Trans-esophagus high-frequency electrostimulation (240-520 impulses/min) of the left atrium was performed in 36 patients in order to arrest the atrial flutter. Immediately after the stimulation, the sinus rhythm was restored in 15 patients (37.5%), and 16 patients (40%) developed atrial fibrillation, 5 patients (12.5%) developed atrial flutter with irregular ventricular rhythm, in 4 patients (10%) the stimulation was ineffective. Subsequently, atrial fibrillation in 3 cases and atrial flutter in 1 case assumed the sinus rhythm. On the whole, the sinus rhythm recovered in 19 (47.5%) cases. Impulses of 20 V proved to be the most effective. This method is effective in cases of an unsuccessful drug antiarrhythmic treatment and electroimpulse therapy. There are no contraindications to this method. It can be successfully employed in cases where electroimpulse therapy is contraindicated or dangerous.
