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.

Introduction: It is rare to find that wide QRS tachycardia automatically changes to narrow QRS tachycardia, and it is more difficult to clarify the mechanism.Case Report: A 3-month-old infant with recurrent paroxysmal supraventricular tachycardia underwent transesophageal cardiac electrophysiological examination. The wide QRS tachycardia was induced by atrial RS2 stimulation, and it soon changed to narrow QRS tachycardia automatically. By the accurate measurement of esophageal lead, it was found that the electrocardiogram changes completely conform to Coumel law. The mechanism of wide and narrow QRS tachycardia was orthodromic atrioventricular reentrant tachycardia with or without ipsilateral functional bundle branch block, and the accessory pathway was defined as the left free wall-concealed accessory pathway.Conclusion: Transesophageal cardiac electrophysiological examination can reveal some special electrophysiological phenomena, and its non-invasive nature is especially suitable for infants.
