Radioiodine Treatment of Paroxysmal Supraventricular Tachycardia in the Euthyroid Patient

Abstract

Twenty-five euthyroid patients subject to recurrent paroxysmal supraventricular tachycardias, which were resistant to usual prophylactic therapy, were treated with radioactive iodine. In many of the patients, with follow-up ranging up to 6 years, there were no recurrences of the tachycardia subsequent to the isotope therapy. Two patients were considered refractory to this therapy.
