Diagnostic Accuracy of Several Electrocardiographic Criteria for the Prediction of Atrioventricular Nodal Reentrant Tachycardia
2016, Archives of Medical ResearchThe supraventricular tachycardias: Proposal of a diagnostic algorithm for the narrow complex tachycardias
2013, Journal of CardiologyCitation Excerpt :A variation of the orthodromic AVRT is the “permanent form of reciprocating junctional tachycardia”, also known as “reciprocating tachycardia of Coumel” [28]. The circuit of this tachycardia includes an accessory pathway at low velocity of conduction (rate-dependent conduction) [29]. This arrhythmia presents a nonparoxysmal but incessant trend and starts whenever the anterograde conduction within the accessory pathway is stopped because of a slightly shorter cardiac cycle [18].
Electrocardiographic differential diagnosis of narrow QRS complex tachycardia: an ED-oriented algorithmic approach
2010, American Journal of Emergency MedicineCitation Excerpt :Narrow complex tachycardias are typically supraventricular in origin, arising from the sinus node, the atria, or the atrioventricular (AV) junction; however, narrow complex ventricular tachycardia has been reported [2]—as this is certainly the exception to the rule, it will not be discussed further herein. Although a number of authors have proposed algorithms to assist in differentiating various NCT types or mechanisms [3-8], these either focus solely on reentrant tachycardias (ie, atrioventricular nodal reentrant tachycardia [AVNRT] and atrioventricular reentrant tachycardia) or are too cumbersome for practical use in the ED setting. In addition, many of these algorithms require the clinician to evaluate several criteria at a single decision point, leading to potential ambiguity.
Supraventricular Tachycardia-Part II: History, Presentation, Mechanism, and Treatment
2008, Current Problems in CardiologyCitation Excerpt :Green et al176 initially reported that alternating changes in the QRS amplitude during a narrow-complex tachycardia is highly suggestive of orthodromic AVRT. This finding was then corroborated by Bar et al.177 However, subsequent investigations by others did not confirm the association between QRS alternans and AVRT. In particular, Kay et al178 found that the incidence of QRS alternans in patients with AVNRT was not significantly different from that in patients with AVRT.
