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.

The records of 28 children whose first episode of paroxysmal supraventricular tachycardia occurred before 12 years (median age 10 months) were reviewed. There were 17 males and 11 females. In 17 cases the first attack occurred before the first year and in 11 of these it occurred after the first year. One case had congenital heart disease (ASD). The WPW syndrome was diagnosed in 3 cases. When first seen, most of the infants presented with signs of incipient or manifest congestive heart failure. In almost ninetenth fo cases rhere was an increased of serum enzymes (lactic dehydrogenase, creatinephosphokinase  and glutamic oxaloaccetic transaminase. Digitals was effective against congestive heart failure and when continued, might prevent failure during subsequent attacks. Antiarrhythmic agents other than digitals were not used. It is recommended to continue digitalis treatment for at least one year in all patients with SVT, whether or not the first episode terminated spontaneously.

Adenosine is frequently used for paroxysmal supraventricular tachycardia (PSVT) treatment in the emergency department (ED). Atrial and ventricular pro-arrhythmic effects of adenosine were described in the literature, but ventricular fibrillation (VF) secondary to adenosine administration was rarely reported (with an incidence of < 1%). Reported herein is the first case of a 72-year-old female patient who developed VF hemodynamic collapse after an intravenous administration of adenosine for PSVT treatment. She had no known pre-excitation or accessory pathway, nor any underlying structural heart disease or prolonged QT syndrome. Raising awareness of this potential life-threatening pro-arrhythmic effect of adenosine is important, given its frequent use for PSVT treatment in the ED.

Supraventricular tachyarrhythmia represents the most frequent fetal dysrhythmia. In the lack of diagnosis and treatment these fetuses may develop hydrops and even death. For the therapeutic approach it is important to establish the diagnosis of the type of supraventricular tachycardia. In this paper we report 29 cases with different types of supraventricular tachycardia in which the diagnosis was established using our own protocol, which allowed us to make the difference between the types of tachycardia (atrioventricular reentry tachycardia due to the accessory pathway, atrial ectopic tachycardia and permanent junctional reciprocal tachycardia). We acquired the data by a series of recordings in M mode and pulsed Doppler by simultaneous recording of an artery and a vein flow. First of all, we diagnosed the supraventricular tachycardia type, with short or long ventriculoarterial interval, and afterwards, we made the difference between atrial ectopic tachycardia and permanent junctional reciprocal tachycardia using methods to decrease the atrioventricular conduction.
