Esophageal atrial pacing can induce and terminate reentrant tachycardia. The author induced by this method and termination of 25 patients 69 cases of paroxysmal supraventricular tachycardia (PSVT), summarized as follows. 1 Materials and Methods General Information The group of 25 patients, 9 males and 16 females, aged 22 to 70 years. 6 cases with coronary heart disease, 1 case of hypertension, 1 case of pre-excitation laser syndrome, I had no organic heart disease. Check the method of induction of supraventricular tachycardia with additional stimulation method: S_1S_2, RS_2, RS_2-S_3R-S_2S_3. S_2 from late diastolic, with 5 ~ 10ms step forward sweep or anti-sweep _2 until can not
