Batutin NT, Diadyk AI, Bagrii AE, Malovichko SI. Kardiologiia 1992 Feb;32(2):64-6. The efficiency of frequent asynchronous transesophageal electrical stimulation (TEES) of the left atrium in atrial flutter of various origin was analyzed in 62 patients. It was found to be depended on the etiology and duration of arrhythmia and on the frequency of atrial waves. The best results were obtained in patients with postmyocardial cardiosclerosis and coronary heart disease in acute arrhythmias and at a low (less than 300 per min) frequency of flutter waves.
