    Die AV-Knoten-Reentrytachykardie (AVNRT) gehört zu den paroxysmalen supraventrikulären Tachykardien.Sie ist gekennzeichnet durch anfallsartig auftretende Tachykardien, die häufig selbstlimitierend sind oder durch einen Vagusreiz terminiert werden können.Sie sind bedingt durch eine zusätzliche Leitungsbahn im AV-Knoten.Die medikamentöse Therapie besteht in einer Verlangsamung der AV ... AV-nodal reentrant tachycardia (AVNRT) is a type of abnormal fast heart rhythm.It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His.AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia. It is more common in women than men (approximately 75% of cases occur in females). There is limited adult data suggesting the tachycardia cycle length (TCL) of AVRT is shorter than AVNRT, though there is little data in children. We sought to determine if there is a difference in tachycardia cycle length (TCL) between AVRT and AVNRT in children.

AVRT is a reentrant tachycardia with an anatomically defined circuit that consists of two distinct pathways, the normal AV conduction system and an AV accessory pathway, linked by common proximal (the atria) and distal (the ventricles) tissues. If sufficient differences in conduction time and refractoriness exist between the normal conduction system and the accessory pathway, a properly timed ...

    A conflict of evidence AVNRT or junctional tachycardia?

    typical AVNRT included central atrial activation, AH in-terval HA (His-atrial) interval, and a septal ventricu-loatrial interval of 40 ms. Despite several radiofrequency energy applications in the region between the os of the coronary sinus and the tricuspid valve annulus that caused slow junctional rhythm, the SVT remained inducible. A versus AVRT over a septal accessory pathway. In AVNRT, the difference between the PPI and the tachycardia cycle length (PPI TCL) is 115 ms.1 Similarly, the difference in the ventriculoatrial (VA) interval during pacing and tachycardia (StimA VA) is 85 ms in AVNRT.1 The opposite is true in AVRT where the PPI TCL is 115 ms, Wolff-Parkinson White Syndrome (WPW) and Atrioventricular reciprocating tachycardia (AVRT) Overview “Wolff-Parkinson White syndrome (WPW)”, refers to a condition where an accessory, or extra, connection exists between the top atria and the bottom ventricles present in less than 1% of the general population, with an associated tachyarrhythmia, or fast heart rhythm.

    There’s only one letter between them, which I find really confusing: AVNRT=AV nodal re-entry tachycardia. AVRT=AV re-entry tachycardia. What’s also confusing is that symptoms of AVNRT and AVRT are pretty similar (and sound like a lot of tachyarrhythmias): lightheadedness, palpitations or a “flutter” in the chest, cough, syncope. You may hear both of them referred to as short or long “RP tachycardia” because of EKG appearance. Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common form of paroxysmal supraventricular tachycardia (PSVT) encountered. It is responsible for approximately 60% to 70% of the different forms of PSVT. AVNRT begins suddenly and im...

    Two forms of AVNRT occur: typical and atypical AVNRT Typical AVNRT (also described as common AVNRT or slow-fast AVNRT): The impulse travels over the slow pathway towards the ventricles and returns via the fast pathway to the atria. The retrograde P wave (or Atrial echo) shows up at the end of the QRS. 90 % of all patients with AVNRT are ... Since the atria and ventricles activate one after another “in sequence” with AVRT as opposed to “in-parallel” as during AVNRT, the interval between the QRS and the P waves is longer in the former, and retrograde P waves are often visible superimposed on the ST-T wave.
