[Rapid transesophageal and transvenous atrial stimulation].

Rapid atrial stimulation (RAS) is a very effective method of treatment of paroxysmal supraventricular tachycardia (PSVT). Substained AV nodal reentrant PSVT could not be terminated by administration of different antiarrhythmic drugs in 19 patients. Transesophageal pacing was performed in 10 patients successfully - in 2 patients following verapamil intravenous administration. In the remaining 7 patients in whom this procedure failed the PSVT could be terminated by transvenous RAS - in 3 patients following the intravenous injection of verapamil.
