Paroxysmal Supraventricular Tachycardia
Practical Cardiology, 2020Supraventricular 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, 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.

Paroxysmal Supraventricular Tachycardia [PDF]
Critical Care Nursing Clinics of North America, 2016 Paroxysmal supraventricular tachycardia (PSVT) is a well-known and thoroughly studied clinical syndrome, characterized by regular tachycardia rhythm with sudden onset and abrupt termination. Most patients present with palpitations and dizziness, and their electrocardiogram demonstrates a narrow QRS complex and regular tachycardia with hidden or ...

Cardiovascular Electrophysiology, 2021
Paroxysmal supraventricular tachycardia (PSVT) encompasses a range of heart rhythm disorders leading to rapid heart rates. By virtue of its episodic nature, diagnosing PSVT is difficult and estimating incidence and prevalence on a population level is ...

Paroxysmal supraventricular tachycardias
The Journal of Emergency Medicine, 1996Paroxysmal supraventricular tachycardia (PSVT) is a distinct clinical syndrome. Most patients present with the abrupt onset of palpitations, dizziness, dyspnea, or chest pain. The electrocardiogram (ECG) demonstrates a fast heart rate (150-250 beats per min), a regular rhythm, and most often, a narrow QRS complex.

Mechanisms of Paroxysmal Supraventricular Tachycardia
Archives of Internal Medicine, 1975Paroxysmal supraventricular tachycardia (PSVT) is a common arrhythmia in patients with and without organic heart disease. It has generally been believed to reflect either reentrant mechanisms or rapid firing of ectopic foci. Recent clinical and experimental observations have suggested that most PSVT appears to reflect reentrance.
