Sinus tachycardia is a condition of multiple different potential etiologies, characterized by an elevated rate of automaticity of the sinoatrial node, such that the heart rate is elevated. The exact point at which sinus tachycardia meets sinus rhythm is debatable; however, by convention, an upper rate of 100 min−1 is accepted for sinus rhythm; >100 ...

Sinus Node Reentrant Tachycardia
Pacing and Clinical Electrophysiology, 1995This review article discusses the electrophysiological basis of sinus node reentry, clinical features of sinus node reentry, and the management of this uncommon tachycardia with drugs and ablative therapy. It also proposes the use of the term “sinoatrial reentrant tachycardia” for this form of tachycardia.

Sinus tachycardia is generally regarded as a symptom and treatment is directed toward the underlying disorder rather than to the tachycardia as such. However, cases are encountered where the cause of the rapid heart action is not clear, or if evident not readily reversible.

Nonreentrant Supraventricular Tachycardia Misdiagnosed as Inappropriate Sinus Tachycardia
Pacing and Clinical Electrophysiology, 2011We report a case of a woman with incessant palpitations initially misdiagnosed as inappropriate sinus tachycardia that proved refractory to β‐blockers. At the time of electrophysiologic testing, a sustained narrow‐complex tachycardia with a 1:2 atrioventricular relationship was repeatedly initiated by a posterior fascicle depolarization induced by ...

Inappropriate Sinus Tachycardia
Cardiology in Review, 2012Inappropriate sinus tachycardia (IST) is an uncommon form of arrhythmia characterized by an increased heart rate that is out of proportion to a normal physiologic demand. The etiology of IST remains ill-defined and controversial. Clinical presentation of IST is highly variable, from isolated to sustained palpitations, and can cause deterioration in one'

Sinus node re-entry and sinus node tachycardia
American Heart Journal, 1975Five patients are reported with SN echoes which could be produced by the technique of APD. The RA was paced at the basic rate and the SEI was measured repeatedly. SN echoes were diagnosed on the basis of: (1) A1A3 interval shorter than the SEI; (2) upright P-waves in Leads II and III; (3) activation of high RA preceding the activation of low RA; (4 ...

Sinus tachycardia masquerading as ventricular tachycardia.
The Tokai journal of experimental and clinical medicine, 1991We describe here a 87-year-old male who came to the emergency room with the chief complaints of dyspnea and chest pain. His electrocardiogram showed a wide QRS tachycardia with a heart rate of 140 beats/min, a left bundle branch block pattern and low voltage in leads I, aVL, V5 and V6.
