The Supraventricular Tachycardias
Annual Review of Medicine, 1988Most supraventricular tachycardias can be diagnosed confidently using the standard 12-lead electrocardiogram, the more so if such a tracing in sinus rhythm is also available. The underlying mechanisms may often be determined and these may have important therapeutic consequences.

Pathophysiology of supraventricular tachycardia
European Heart Journal, 1993Supraventricular tachycardia is due to altered automaticity, triggered activity or most commonly, reentry. Atrial flutter is most frequently due to reentry with counterclockwise activation in the right atrium with the left atrium acting as a bystander.

Classification of supraventricular tachycardias
The American Journal of Cardiology, 1987An ideal approach to classification of supraventricular arrhythmias would be based on exact knowledge of the pathophysiology and mechanism of the arrhythmia. Unfortunately, the mechanism may not be apparent from electrocardiographic data or indeed may not be known after extensive invasive and non-invasive studies.

Irregular Supraventricular Tachycardia
JAMA Internal Medicine, 2013An86-year-oldwomanwithaknownhistoryofcoronaryarterydisease and a prior percutaneous coronary intervention presented to the emergency department with several episodes of selfresolving chest discomfort occurring at rest. She denied any shortness of breath, palpitations, and diaphoresis. Her home medications included a β-blocker.

Spectrum of supraventricular tachycardias
The American Journal of Cardiology, 1988The term "supraventricular tachycardia" includes a wide variety of arrhythmias with very different clinical and prognostic significance. Each supraventricular tachycardia has unique characteristics and each patient, even when similar arrhythmias are present, remains a person with specific manifestations. In 1988, physicians should not be satisfied with

Intrauterine supraventricular tachycardia
The Journal of Pediatrics, 1979Six examples of intrauterine supraventricular tachycardia together with 31 previously reported cases are described and analyzed. Among the 37 infants, structural heart disease was present in only four (11%), three of whom died. Males comprised 68% of the group without identifiable heart disease or pre-excitation. Congestive heart failure was evident in

Introduction to Supraventricular Tachycardia
Cardiac Electrophysiology Clinics, 2010Paroxysmal supraventricular tachycardia (PSVT) is a clinical syndrome characterized by a rapid tachycardia with an abrupt onset and termination cardiomyopathy. The three most common causes of PSVT are atrioventricular nodal reentrant tachycardia (50%-60%), atrioventricular reentrant tachycardia in patients with Wolff-Parkinson-White syndrome (25%-30%),

Adenosine and Supraventricular Tachycardia
New England Journal of Medicine, 1991ADENOSINE is an endogenous nucleoside that is capable of causing atrioventricular nodal conduction block in humans.1 Although the use of intravenous adenosine to terminate supraventricular arrhythmias was first described in 1933,2 it is only in the past 8 years that adenosine has been investigated in detail3 and only in the past 18 months that it has ...

Supraventricular tachycardia in children
The Indian Journal of Pediatrics, 2005Several different mechanisms are responsible for paroxysmal supraventricular tachycardia in children. Different forms of tachycardia occur at different age. Atrio-ventricular reentry tachycardia results from the presence of congenital atrio-ventricular bypass tracts and is frequently encountered at all ages.

Mechanisms of supraventricular tachycardia
The American Journal of Cardiology, 1988Programmed electrical stimulation of the heart in combination with intracardiac recordings has contributed a wealth of new information on the mechanisms and pathways of supraventricular tachycardia in humans. This knowledge has resulted in better treatment approaches to these patients.
