title: [High-frequency electric stimulation of the atrium in treatment of supraventricular tachycardias and atrial flutter].
abstract: The authors report the results of rapid atrial stimulation in the treatment of 12 cases of junctional tachycardia (J.T.), 20 cases of atrial tachycardia (A.T.) and 43 cases of atrial flutter (A.F.). Sinus rhythm was restored in 91.6%, 70% and 60.4% of the cases for J.T., A.T. and A.F. respectively, either when pacing was discontinued or following a period of atrial fibrillation (from a few minutes to several hours). Fifteen per cent of the cases of A.T. and 25.5% of the cases of A.F. turned into stable atrial fibrillation with reduction of ventricular rate. The authors believe that this technique is a valuable alternative to D.C. countershock when medical treatment has proved ineffective and when countershock may be hazardous.
