Supraventricular Tachycardias

Supraventricular tachycardias (SVTs) comprise a group of usually benign arrhythmias that originate from cardiac tissue at or above the His bundle. SVTs include inappropriate sinus tachycardia, atrial tachycardias (ATs), atrial flutter (AFL), junctional tachycardia, atrioventricular nodal reentrant tachycardia (AVNRT), and forms of accessory pathway–mediated reentrant tachycardias (atrioventricular reentrant tachycardia [AVRT]). Although mostly benign, symptoms can be debilitating, in the form of palpitations, shortness of breath, chest discomfort, dizziness, and/or syncope; rarely, SVTs can result in cardiomyopathy due to incessant arrhythmia. This review covers the epidemiology, diagnosis, management, and classification of SVTs.  This review contains 14 figures, 17 tables, and 61 references.

Focal Atrial Tachycardia

Focal atrial tachycardia is a relatively uncommon paroxysmal supraventricular tachycardia. Although atrioventricular conduction is regularly 1:1 and the PR interval is often in the normal range, occasionally a 1:1 atrial tachycardia may have a short RP interval, especially when the heart rate is particularly high or the atrioventricular conduction is markedly increased. In these cases, it is necessary to differentiate focal atrial tachycardia from common atrioventricular nodal reentrant tachycardia , which is the most frequent form of paroxysmal supraventricular tachycardia. We describe a case of unusual focal atrial tachycardia with a short RP interval (< 90 ms) in a patient with a marked AV first-degree block which simulates a typical atrioventricular nodal reentrant tachycardia.

Background: Superior-type fast-slow (sup-F/S-) atrioventricular nodal reentrant tachycardia (AVNRT) is a rare AVNRT variant using a superior slow pathway (SP) as the retrograde limb. Its intracardiac appearance, characterized by a short atrio-His (AH) interval and the earliest site of atrial activation in the His-bundle, is an initial indicator for making a diagnosis. Methods: Among 22 consecutive patients with sup-F/S-AVNRT, 3 (age, 68–81 years) patients had an apparent slow-fast (S/F-) AVNRT characterized by a long AH interval and the earliest site of atrial activation in or superior to the His-bundle region (tachy-long-AH). Results: The diagnosis of sup-F/S-AVNRT was based on the standard criteria in 2 patients and on the occurrence of Wenckebach-type atrioventricular block during tachycardia, which was attributable to a block at the lower common pathway (LCP) below the circuit of the AVNRT, detected owing to the lower common pathway potentials, in one patient. As with the typical S/F-AVNRT, tachy-long-AH was induced after a jump in the AH interval. In contrast to typical S/F-AVNRT, fluctuation in the ventriculoatrial interval was observed during the tachy-long-AH. Ventricular overdrive pacing was unable to entrain or terminate the tachy-long-AH. Moreover, the tachy-long-AH reciprocally transited to/from sup-F/S-AVNRT spontaneously or was triggered by ventricular contractions while the atrial cycle length and earliest site of atrial activation remained unchanged. Both tachycardias were cured by ablation at a single site in the right-side para-Hisian region of 2 patients and the noncoronary aortic cusp of one patient. Collectively, the essential circuit of both tachycardias was identical, and the tachy-long-AH was diagnosed as another phenotype of sup-F/S-AVNRT accompanied by sustained antegrade conduction via another bystander slow pathway breaking through the His-bundle owing to the repetitive antegrade block at the lower common pathway, thus representing a long AH interval during the ongoing sup-F/S-AVNRT. Conclusions: An unknown sup-F/S-AVNRT phenotype exists that apparently mimics the typical S/F-AVNRT and is also an unknown subtype of apparent S/F-AVNRT.
