Paroxysmal Supraventricular Tachycardia

2020
Supraventricular tachycardias arise in or involve at least some part of the atrium or atrioventricular junction. Supraventricular tachycardias develop as a result of abnormal automaticity, triggered activity or, most commonly, reentry. Both atrial flutter and atrial fibrillation are supraventricular tachycardias; however, because of the differences in ...

Essentials of Paroxysmal Supraventricular Tachycardia for the Pediatrician

Pediatric Annals, 2021
Paroxysmal supraventricular tachycardia (SVT) is the most common clinical arrhythmia in young patients. With an estimated prevalence of roughly 1 in 500 children, a pediatrician may knowingly or unknowingly see several patients who are affected each year.

Effect of pregnancy on paroxysmal supraventricular tachycardia

The American Journal of Cardiology, 1993
more detailed study is undertaken. In the present study, 24% (6 of 25) of patients had either dual AV node pathways or multiple accessory pathways. In such cases, the initial use of an abbreviated protocol may actually prolong the procedure. One additional point merits consideration.

Chronobiology of Symptomatic Supraventricular Paroxysmal Tachycardia

Biological Rhythm Research, 1998
The circadian, circaseptenal and circaannual occurrence of supraventricular paroxysmal tachycardias (SVPT) were examined in patients addressing an Emergency Department. Sixty-one patients, 22 men and 39 women aged 48.3+13.0 y, were eligible and investigated during a solar year.

Mechanisms and Management of Paroxysmal Supraventricular Tachycardia

Cardiology in Review, 1999
Paroxysmal supraventricular tachycardia (PSVT) is defined as a regular rapid heart beat, which initiates and terminates suddenly. PSVT may have a variety of electrophysiologic mechanisms, including atrial tachycardia, atrioventricular (AV) nodal reentry, and tachycardia involving an accessory AV connection. Atrial tachycardia may be reentrant or may be

Pirmenol in the termination of paroxysmal supraventricular tachycardia

The American Journal of Cardiology, 1987
The effects of pirmenol in terminating paroxysmal supraventricular tachycardia were studied in 25 patients. Pirmenol was administered as 1 or 2 injections of 50 mg to 17 patients during a spontaneous attack, or as a 50-mg bolus followed by steady infusion of 2.5 mg/min in 8 patients during a tachycardia that was induced electrophysiologically ...

[Paroxysmal supraventricular tachycardia].

Anales espanoles de pediatria, 1991
We report 65 cases (1970-1989). They were processing in a data base program for cardiology records. A number of selected variables, were analysed by un statistical package. The results of 230 statistical tests between means, percentage and correlations, point out statistical value on prognosis forecast.

Paroxysmal Supraventricular Tachycardia: Experience with Propafenone

Angiology, 1989
The authors studied the efficacy of intravenous (IV) (1.5-2 mg/kg) and oral propafenone (450 to 900 mg/day) in 16 patients with paroxysmal, sus tained, recurrent supraventricular tachycardia (SVT). In 5 patients IV propafenone was not given, because of intolerant SVT. Nine patients had Wolff-Parkinson-White syndrome.

An approach to therapy for paroxysmal supraventricular tachycardia

The American Journal of Cardiology, 1988
A variety of options are available for managing recurrent paroxysmal supraventricular tachycardia. These options include empirical drug therapy on a trial and error basis, drug therapy based on the results of electrophysiologic testing and nonpharmacologic treatment including operative therapy, catheter ablation and antitachycardia devices.

Paroxysmal Supraventricular Tachycardia

2018
1. An aberrant conduction pathway between ventricles and atria allows impulses to be conducted in a circular pathway, without involving the SA node. The ECG shows rapid, narrow complexes without visible p-waves. 2. Paroxysmal supraventricular tachycardia (PSVT) has become nearly synonymous with its most common variant, called ...
