摘　　要：Sixty-six cases with reentrant supraventricular tachycardias were treatedby radiofrequency current cather ablation(RFCA).Forty one patients withatrioventricular reentrant tachycardia(male 30,femal 11,Group Ⅰ),Twenty fivepatients with atrloventricular nodal reentrant tachycaria(male 8,femal 17,Group Ⅱ).Group 1.41 patients had 43 accessory pathways(APs)of which23 located at left free wall(53.5),6 at left posteroseptal region(13.9%),14 atright free wall(32.6%).Successful RFCA were 26 in 27 cases with leftAPs(96.3%),14 in 14 cases with right APs(100%).In group 11.13 patientswith slow pathway were ablated,success rate is 92.3.The characteristics of local electrocardlogram at the ablation target sitewere:(1)A/V ratlo【1.(2)AV or VA Interval【40ms.(3)V-delta Interval】20ms.the 95%ablation target sites were slmler to this characteristics in oursuccessful RFCA.During a follow up of 1-7months,no Patients hadexparienced recurrence of arrhythmia.Sixty-six cases with reentrant supraventricular tachycardias were treated by radiofrequency current cather ablation(RFCA).Forty one patients with atrioventricular reentrant tachycardia(male 30,femal 11,Group Ⅰ),Twenty five patients with atrloventricular nodal reentrant tachycaria(male 8,femal 17, Group Ⅱ).Group 1.41 patients had 43 accessory pathways(APs)of which 23 located at left free wall(53.5),6 at left posteroseptal region(13.9%),14 at right free wall(32.6%).Successful RFCA were 26 in 27 cases with left APs(96.3%),14 in 14 cases with right APs(100%).In group 11.13 patients with slow pathway were ablated,success rate is 92.3. The characteristics of local electrocardlogram at the ablation target site were:(1)A/V ratlo<1.(2)AV or VA Interval<40ms.(3)V-delta Interval>20ms. the 95%ablation target sites were slmler to this characteristics in our successful RFCA.During a follow up of 1-7months,no Patients had exparienced recurrence of arrhythmia.
