Paroxysmal Supraventricular Tachycardia in an Octogenarian
The Journal of Emergency Medicine, 2012Paroxysmal supraventricular tachycardia is a common dysrhythmia that occurs at all ages. Its management is determined by presenting symptoms and previous history of the patient. Patients present with a continuum of symptoms ranging from palpitations to syncope.

Fatal Paroxysmal Supraventricular Tachycardia in an Infant
Chest, 1986A 37-day-old infant, without associated congenital anomalies, died following a 48-hour episode of supraventricular tachycardia. The histopathologic findings of nodoventricular and fasciculoventricular Mahaim's fibers in a setting of persistent fetal dispersion were consistent with an anatomic substrate for a reentry circuit at the specialized A-V ...

Perinatal Paroxysmal Supraventricular Tachycardia
Scottish Medical Journal, 1983Three cases of perinatal paroxysmal supraventricular tachycardia are described. In two patients the tachycardia was present prior to delivery; in the third baby, who also had the Wolf-Parkinson-White Syndrome, the time of onset of tachycardia is not known.

Circadian Variation of Paroxysmal Supraventricular Tachycardia
Chest, 1999Various clinical manifestations of cardiovascular diseases have a pattern of circadian variation. In this study, we investigated whether the onset and duration of paroxysmal supraventricular tachycardia (PSVT) has a circadian variation.In our analysis, we included 105 patients with 498 PSVT episodes.

Pirmenol in the termination of paroxysmal supraventricular tachycardia
The American Journal of Cardiology, 1987The 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 ...

Chronobiology of Symptomatic Supraventricular Paroxysmal Tachycardia
Biological Rhythm Research, 1998The 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.

Essentials of Paroxysmal Supraventricular Tachycardia for the Pediatrician
Pediatric Annals, 2021Paroxysmal 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, 1993more 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.

PHENYLEPHRINE HYDROCHLORIDE IN PAROXYSMAL SUPRAVENTRICULAR TACHYCARDIA
Journal of the American Medical Association, 1955Phenylephrine (Neo-Synephrine) hydrochloride was first suggested as an effective drug in the treatment of paroxysmal supraventricular tachycardia by Youmans and his group in 1947. Since this time others have mentioned its use and at the same time suggested that the drug was relatively innocuous in the absence of heart disease.

Paroxysmal Supraventricular Tachycardia: Experience with Propafenone
Angiology, 1989The 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.
