[Transitory transesophageal atrial electric stimulation. Preliminary report on 19 cases and considerations on the method, indications and results (author's transl)].
Literature provides sufficient evidence that transitory electric stimulation via esophagus (SATE) - after the first positive experimental attempts on dogs - can be applied to man with a simple, rapid and harmless method. The study covers 19 patients subjected to high frequency transesophageal atrial stimulation by way of a bipolar electrode inserted through a nasogastric tube and connected to an external generator capable of producing tension impulses. Said impulses are variable up to 150 volts, lasting 2.5 microsec. with a frequency of up to 450/min. The 19 patients can be divided into 2 groups. The first including 15 patients on which SATE was effected for diagnostic purposes: in coronary deficiency (8 patients), in the disease of sinus node (3 patients), and lastly in the research for the A-V-block latent in 4 patients with acute post-infarctual A-V-block which regressed during the immediate clinical course of the illness. The other group includes 4 patients in which the atrial stimulation indication was the treatment of rapid, paroxysmic atrial rhythms, inaffected by drugs. By using impulses of 25-30 volts, the AA. have obtained a stable stimulation.
