Atrioventricular nodal re-entry tachycardia is a common supraventricular arrhythmia. The rate of recurrence is relatively high, and accordingly ablative therapy became the first-line suggested therapy. In this review, we highlight the electrocardiographic clues to the diagnosis of atrioventricular nodal re-entry tachycardia, also we present the electrophysiological data and maneuvers that enabl...

Distinction between ventricular tachycardia (VT) and supraventricular tachycardia (SVT) with aberrant conduction has major therapeutic and prognostic implications. Exclusive assessment of lead aVR, using a fourstep algorithm can rapidly make such distinction with a high degree of diagnostic accuracy. To illustrate the concept, we present the case of a 70-year-old female with a prior history of ...

Fragments of Holter monitoring a 64-year-old patient with paroxysms supraventricular tachycardia are presented, atrial ectopic activity during is recorded, which does not interrupt the tachycardia, but changes sequence RR intervals. The possibility remote analysis data 3-day patient’s electrocardiogram in 12-channel provided.

Intravenous adenosine triphosphate rapidly terminated all 11 episodes of paroxysmal supraventricular tachycardia in 10 patients. Eight patients reported side effects but these resolved within 20 seconds and did not require treatment. Adenosine triphosphate is a suitable agent for the rapid termination of paroxysmal supraventricular tachycardia.

DURING experimentally induced supraventricular tachycardia Moe and associates' observed in the dog heart aberrant conduction in one of the bundle branches, caused by retrograde invasion into that bundle branch, causing functional bundlebranch block. As far as we know no clinical record has been reported. Recently we saw a patient with supraventricular tachycardia and left aberrant conduction, p...

OBJECTIVES To clarify the prevalence and mechanism of supraventricular tachycardia in patients with right atrial isomerism. BACKGROUND Paired SA and dual atrioventricular (AV) nodes have been described in patients with right atrial isomerism. However, the clinical significance remains unclear. METHODS From 1987 to 1996, a total of 101 patients (61 male, 40 female) and four fetuses were iden...

Background: Arrhythmias in neonates are not common and usually affect newborns with a normal heart or those that suffer from structural heart disease. A malignant type of arrhythmias is supraventricular tachycardia. Meanwhile, one uncommon type of supraventricular arrhythmias is atrial flutter (AFL), which is founded upon reentry mechanisms in the atrium. The AFL may result in heart failure or ...
