The worldwide initial success rate for RFCA was reported as 90% to 95% in patients with WPW syndrome13,17,18 and 98% to 100% in AVNRT
Atrioventricular nodal reentrant tachycardia (AVNRT
) is the most common of paroxysmal supraventricular tachycardia (PSVT) in adults6,7.
Examples of a short RP tachycardia include: typical AVNRT
, AVRT or AT.
We examined 43 patients hospitalized at the Tertiary Medical Center of Cardiology, Uzbekistan Public Health Ministry, diagnosed with AVNRT
of "slow-fast" type, 12 (12.9%) men and 31 (72.1%) women among them (mean age 40.6 [+ or -] 2.25 years; Me 40 years; Interquartile Range (IQR) 31.0-52.5) with mean arrhythmia duration in medical history of 11.3 [+ or -] 1.11 years (Me 10 years, IQR 6.0-15.0).
Results of success frequency for different types of arrhythmia in their study were as: AVNRT
98% (130/132), AVRT 91% (97/106), typical atrial flutter 99% (129/130) and for atrial tachycardia 86% (18/21).15 Results of success frequency for different types of arrhythmia in our study included AVNRT
100% (28/28), AVRT 100% (17/17), and for atrial tachycardia 75% (3/4).
Bizim vakamizda cift AV iletim fizyolojisine eslik eden AVNRT

Those in which the RP interval is longer than the PR interval are called long RP tachycardies and include sinus tachycardia, intra-atrial tachycardia, atypical AVNRT
, and AVRT with a slowly conducting ventriculoatrial pathway.
On that basis, your SVT is most likely an atrioventricular nodal reentrant tachycardia (AVNRT
) and is due to your heart impulse occasionally taking a wrong turn at the middle of your heart and ending up like a cat chasing its tail.
For example, palpitations that are regular and paroxysmal in nature, with abrupt onset and cessation or termination of symptoms with vagal maneuvers, are suggestive of atrioventricular reciprocating tachycardia (AVRT) or AV nodal reciprocating tachycardia (AVNRT

PSVT comprises many types of arrhythmias, the most common ones being atrioventricular nodal re-entrant tachycardia (AVNRT
) and atrioventricular re-entrant tachycardia (AVRT) .
Results: In 536 of the 800 patients the supraventricular tachycardia substrate was an AVNRT
(67%), in 236 patients an AVRT (29.5%) and in 28 patients an AT (3.5%).
CAG and EPS showed normal epicardial coronary arteries and atrioventricular node reentry (AVNRT
), respectively; and slow pathway ablation was performed successfully.
Joseph's has used the system to treat nearly 60 patients with a variety of arrhythmias, including AVNRT
, AVRT and Atrial Tachycardia.
