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 ...

Cardiomyopathy secondary to sinus tachycardia
International Journal of Cardiology, 1993We describe a case of cardiomyopathy resulting from a tachycardia of high-right atrial origin indistinguishable from sinus tachycardia. The symptoms and angiographic appearances improved dramatically with beta blockade.

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 ...

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 ...

Archives des maladies du coeur et des vaisseaux, 2005
Various tachycardias presenting with positive P waves in the standard leads are described in this article. Sinus tachycardia may occur as a normal adaptation reaction to the environment or in the setting of autonomic dysregulation. It may also be mimicked by various arrhythmias which share the earliest depolarisation in the sinus node area. The authors

[Inappropriate sinus tachycardia].
Deutsche medizinische Wochenschrift (1946), 2015Inappropriate sinus tachycardia is characterized by an unexplained increase of the resting sinus rate (> 100 bpm) with excess increase in response to moderate activity (mean heart rate > 90 bpm/24 h). Affected patients may suffer from heart race, palpitations, fatigue, weakness and dizziness.

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.
