Supraventricular Arrhythmias in Emergency
2015The term “supraventricular tachycardia” refers to arrhythmias requiring atrial or atrioventricular nodal tissue, or both, for their initiation and maintenance. Supraventricular tachycardias are often recurrent, occasionally persistent, and a frequent cause of visits to emergency departments (ED) [1].

Effective treatment of supraventricular arrhythmias with acebutolol
The American Journal of Cardiology, 1979To evaluate the antiarrhythmic efficacy of the new beta adrenergic blocking agent acebutolol, 15 monitored patients with supraventricular arrhythmias received, in double-blind fashion, an intravenous infusion of either acebutolol or saline solution after a control period. Patients treated with saline solution demonstrated no change (P greater than 0.05)

Atrial fibrillation and supraventricular arrhythmias
2015This chapter discusses the acute management of patients presenting with tachyarrhythmias suggestive of regular supraventricular tachycardias (SVT) and/or atrial fibrillation (AF). A classification of narrow- and wide-QRS tachycardias is presented, and the differential diagnosis of narrow- and wide-QRS tachycardias is discussed.

Magnetocardiography: Supraventricular arrhythmias and preexcitation syndromes
European Heart Journal, 1993Magnetocardiography is an elegant non-invasive method with which to study the electrical activity of the heart. The localization of cardiac electric sources, such as arrhythmia foci, would, in particular, be an interesting clinical application.

Dofetilide promising in supraventricular arrhythmias [PDF]
Inpharma Weekly, 1998 The class III antiarrhythmic agent dofetilide shows potential in a variety of supraventricular arrhythmias. It appears to have a satisfactory adverse effect profile with low proarrhythmic potential and no negative inotropic effects. The results of a number of studies examining the use of dofetilide in supraventricular arrhythmias were presented at the ...

Catheter Ablation Therapy for Supraventricular Arrhythmias
JAMA, 2007The supraventricular arrhythmias include a wide spectrum of disorders including, in descending order of frequency, atrial fibrillation, atrial flutter, atrioventricular nodal reentry, Wolff-Parkinson-White syndrome, and atrial tachycardia. While not life-threatening in most cases, they may cause important symptoms, such as palpitations, chest ...

Mechanism of action of sotalol in supraventricular arrhythmias
Cardiovascular Drugs and Therapy, 1990Sotalol has a virtually unique antiarrhythmic profile in that it combines the properties of the Class II beta-blocking agents with the Class III properties that prolong repolarization. The Class II action exerts a marked effect on atrioventricular nodal conduction and makes sotalol a suitable drug for the treatment of adrenergic-induced ...

Supraventricular and Ventricular Arrhythmias
2001Atrial tachyarrhythmias are the most common arrhythmias occurring in ICU patients, with a reported prevalence of 28%. Atrial fibrillation (AF) is the most common atrial arrhythmia (52%) followed by atrial flutter (27%) and multifocal atrial tachycardia (MAT). Since the etiology and management strategies of atrial fibrillation and atrial flutter overlap,

Electrophysiology of beta blockers in supraventricular arrhythmias
The American Journal of Cardiology, 1987beta-adrenergic blocking agents are efficacious in the treatment of patients with a variety of supraventricular tachycardias, based directly on their capacity to counter the effects of beta-adrenergic stimulation on sinus and atrioventricular nodal tissue.

[Nonpharmacological therapy of supraventricular arrhythmia].
Cardiologia (Rome, Italy), 1991Between 1985 and 1990, 1242 patients with supraventricular arrhythmias were followed-up at our Institution. Six hundred and twenty patients had atrial fibrillation or flutter; 7 of them (1%) underwent modulation of atrioventricular conduction. Four hundred and twenty-eight patients had ventricular preexcitation; in 23 (5%) surgical or transcatheter ...
