[Validity of the radiofrequency programmed stimulation in the treatment of the sick sinus syndrome. (author's transl)].

It is presented a patient sick sinus syndrome with the periods of the sinus bradycardia and of the superventricular tachycardia, treated with the implanted of a permanent ventricular inhibited pacemaker and a passive radio- receiver connected with a ventricular electrocatheter. The tachycardia was interrupted by ventricular way with a discharge of beaths high frequency, utilizing a radiofrequency device connected with a exterior programmed stimulation. It is solicited a more large employment of the radiofrequency stimulation's system in the relapsing and persistent tachycardia, alternately with the pharmacologyc therapy and the DC shock.
