A study reported 10-year data of EPS and RFCA done in 2012 with a success rate of 99% in AVNRT
and 94% in AVRT, while major complications were 0.45% including 3 patients requiring permanent pacing.
Among SVT common arrhythmias were atrial tachycardia (AT) 50 (17.5%) and atrioventricular nodal re-entry tachycardia (AVNRT
) 38 (13.2%), while Atrioventricular re-entry tachycardia (AVRT) and atrial flutter (AFL) were less common found in 30 (10.4%) and 8 (2.8%) cases, respectively, as shown in table-I.
If the SVT starts with a very long PR interval at the onset of the tachycardia, the clinician should diagnose AVNRT
with antegrade slow pathway conduction accounting for the prolonged PR interval.
We have managed to analyze RFA early and late outcomes in 43 examinees with typical AVNRT
. One-year follow-up demonstrated that the procedure was efficient in 40 patients (93.0%).
A further patient with AVNRT
had transient complete heart block that lasted for less than 24 hours.

Studies have proven that PSVT due to AVNRT
in older subjects is often related to an atrioventricular conduction abnormality, the longer AVN conduction intervals and refractory period explaining the late development of AVNRT
, AVRT, AT, Radiofrequency ablation, Supraventricular tachycardia.
Last month, the Food and Drug Administration approved the Freezor Cryoablation System specifically for treatment of atrioventricular node reentry tachycardia (AVNRT
Objective: Atrioventricular nodal reentrant tachycardia (AVNRT
) accounts for about 60% of the patients presenting with paroxysmal supraventricular tachycardia.
