Case report The patient was a male infant born at 38 weeks’ gestation. Atrial flutter was diagnosed in utero at 35 weeks of gestation, at which time no hydrops fetalis was present and no treatment was commenced. At 6 hours of life, the infant developed tachycardia. The electrocardiogram (ECG) showed atrial flutter with 2:1 atrioventricular conduction (Figure 1). Initially the rhythm could be re...

avnrt, (atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. a 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. radiofrequency ablation of the slow pathway territories cured all of them. there...

OBJECTIVES We tested the hypothesis that the response to flecainide infusion can identify patients with atrial fibrillation (AF) in whom the hybrid pharmacologic and ablation therapy reduces the recurrences of AF. BACKGROUND Infusion of class IC anti-arrhythmic drugs may promote transformation of AF into atrial flutter. Catheter ablation of atrial flutter has been demonstrated to be highly ef...

A 25-year-old man with idopathic atrial flutter and high grade atrioventricular (AV) block is described. Postcardioversion, sino-atrial (SA) and AV nodal dysrhythmias occurred. Treadmill exercise during atrial flutter increased AV conduction to 2:1, and normalized SA and AV nodal function following cardioversion. A neurogenic basis for these arrhythmias is hypothesized.

This article reviews the safety and efficacy of ibutilide for use in patients with atrial fibrillation and flutter. Ibutilide, a class III antiarrhythmic agent, is primarily used for conversion of atrial flutter and fibrillation and is a good alternative to electrical cardioversion. Ibutilide has a conversion rate of up to 75% to 80% in recent-onset atrial fibrillation and flutter; the conversi...

The electrophysiologic determinants of conversion and the prevention of atrial flutter are poorly defined. This issue was therefore investigated by evaluating the effects of the new class III antiarrhythmic drug d-sotalol and the class I antiarrhythmic drugs quinidine and lidocaine. Atrial flutter was reproducibly induced in the open-chest anesthetized dog with intercaval crush and rapid atrial...

BACKGROUND The occurrence of atrial fibrillation after ablation of type I atrial flutter remains an important clinical problem. To gain further insight into the pathogenesis and significance of postablation atrial fibrillation, we examined the time to onset, determinants, and clinical course of atrial fibrillation after ablation of type I flutter in a large patient cohort. METHODS AND RESULTS...

Atrial flutter is a common arrhythmia that may cause significant symptoms, including palpitations, dyspnea, chest pain and even syncope. Frequently it's possible to diagnose atrial flutter with a 12-lead surface ECG, looking for distinctive waves in leads II, III, aVF, aVL, V1,V2. Puech and Waldo developed the first classification of atrial flutter in the 1970s. These authors divided the arrhyt...

Dual-loop macro-reentry atrial flutter (AFL) is an atypical AFL, which has two loops of the reentry circuit usually localized within single atrium. In this case report, we present a double-loop bi-atrial flutter during atrial fibrillation ablation, in which the two reentry circuit loops were located around the inferior vena cava (IVC) and the mitral annulus, (MA) respectively.
